क्या। पृष्ठ अनुवाद सुविधा की मदद से विकि के पृष्ठों को दूसरी भाषा में नियंत्रण के अंतर्गत अनुवादित किया जा सकता है। इसका मतलब है कि हर अनुवाद की सामग्री आम तौर पर स्रोत पृष्ठ के बराबर होगी। यह विकिपीडिया के लेखों के अलग-अलग भाषा संस्करणों से अलग है, जो एक-दूसरे से पूरी तरह से स्वतंत्र हैं। यह माना जाता है कि पृष्ठों का सिर्फ एक प्राथमिक भाषा से दूसरी भाषाओं में अनुवादित किया जाता है, लेकिन अगर भाषाओं में भी अनुवाद मौजूद हों तो अनुवादक उनका का फ़ायदा उठा सकते हैं।

क्यों। किसी भी मदद के बिना, कुछ भाषाओं में कुछ पृष्ठों से अधिक अनुवादित करना बस समय की बर्बादी होती है, और ज़्यादा से ज़्यादा अनानुरक्षित कचरा। पृष्ठ अनुवाद सुविधा के साथ आप कचरे से बच सकते हैं और अनुवाद प्रक्रिया में संरचना ला सकते हैं। मूल विचार यह है कि स्रोत टेक्स्ट को छोटी इकाइयों में विभाजित किया जाता है, जिनमें से हर इकाई को एक-एक करके अनुवादित किया जाएगा। जब स्रोत टेक्स्ट को इकाइयों में विभाजित किया जाता है, तो सभी बदलाव अलग किए जा सकते हैं और अनुवादकों को सिर्फ उन इकाइयों के अनुवादों को अपडेट करना होगा, जिनमें स्रोत टेक्स्ट में बदलाव हुए हैं। यह अनुवादकों को प्रबंधनीय आकार की इकाइयों पर काम करने और कई अनुवादकों के बीच काम साझा करने या बाद के सत्रों में अनुवाद जारी रखने में सक्षम बनाता है, क्योंकि उन्हें एक साथ सभी को करने की ज़रूरत नहीं होती है।

कौन। यह पृष्ठ, सिस्टम के कार्यों पर गहरी जानकारी प्रदान करके और कई मामलों के लिए सर्वोत्तम प्रथाएँ बताकप पृष्ठ अनुवाद ट्यूटोरियल को विस्तृत करता है। यह पृष्ठ पृष्ठ अनुवाद प्रबंधकों के लिए है और आम तौर पर उन सभी के लिए जो अनुवाद-योग्य पृष्ठों के स्रोत टेक्स्ट को सम्पादित करते हैं, भले ही उनके पास अनुवाद के लिए बदलावों को स्वीकार देने के प्रबंधन सुविधाओं तक पहुँच न हो।

एक अनुवाद-योग्य पृष्ठ का जीवन
भूमिकाएँ। एकाधिक लोग विकि पृष्ठों को लिखने और अनुवादित करने की प्रक्रिया में शामिल हैं: शुरुआती लेखक एक पृष्ठ बनाता है, कोई वर्तनी त्रुटियों को सुधारता है, एक पृष्ठ अनुवाद प्रबंधक अनुवाद के लिए पृष्ठ को चिह्नित करता है, अनुवादक अनुवाद करता है, कोई पृष्ठ पर बदलाव लाता है, एक पृष्ठ अनुवाद प्रबंधक उन बदलावों को अनुवाद के लिए चिह्नित करता है और अनुवादक अनुवादों को अपडेट करते हैं। उन भूमिकाओं में ओवरलैप हो सकता है, लेकिन पृष्ठ के अनुवाद को आसान बनाने का काम अनुवाद प्रबंधक पर छोड़ दिया जाता है। प्रबंधक फैसला लेता है कि पृष्ठ पहली बार अनुवाद के लिए कब तैयार होगा, सुनिश्चित करता है कि विभाजन अपना काम ठीक से कर रहा है, और बदलाव स्वीकार करता है (या सुधारता है)।

तैयारी। कुछ अनुवाद करने के लिए आपको पहले उसे लिखना होगा। अगर आपने अनुवाद एक्सटेंशन के बिना पहले ही अनुवाद कर लिया है, नीचे अनुवादों को माइग्रेट करने के बारे में अनुभाग देखें। अगर आप चाहते हैं कि जल्दी से जल्दी अधिक अनुवाद आए, स्रोत टेक्स्ट का साफ़-सुथरा होना ज़रूरी है। किसी पृष्ठ को अनुवाद के लिए चिह्नित करने से पहले किसी और से कहें कि वह पृष्ठ को एक बार पढ़ें, और किसी भाषा-विशेषज्ञ से कहें कि वह टेक्स्ट को स्पष्ट बना दें। कठिन शब्दावली और समझने में कठिन वाक्य कई स्वयंसेवक अनुवादों को प्रभावशाली प्रदर्शन करने से रोकता हैं। मार्कअप से भी अनुवादकों को समस्याएँ आ सकती हैं, मगर अनुवाद प्रबंधक होने के नाते आप ऐसी समस्याओं से बच सकते हैं। नीचे मार्कअप को हैंडल करने के बारे में अनुभाग देखें। अनुवादों के स्रोत टेक्स्ट में बदलाव होने पर बेशक अनुवादों में भी बदलाव की ज़रूरत होगी, तो पृष्ठ की सामग्री के स्थिर हो जाने तक इंतज़ार करना बेहतर है। मगर बदलाव होते रहते हैं, और सिस्टम उन्हें अच्छी तरह से हैंडल कर लेता है, तो नीचे बदलावों को हैंडल करने के बारे में अनुभाग देखें।

टैग करना। जब टेक्स्ट अनुवाद के लिए तैयार हो जाता है, कोई भी अनुवाद-योग्य हिस्सों को टैग्स में लपेटकर और पृष्ठ पर  बार जोड़कर चिह्नित कर सकता है। बार के टैग से पृष्ठ के सभी अनुवादों की एक सूची जोड़ दी जाती है, जिसमें उनकी पूर्णता और अद्यत प्रतिशत दिखाई जाती है। और ऐसा कोई चिह्न नहीं जो बताता हो कि अनुवाद मौजूद हैं। नीचे देखें कि टैग असल में करना कैसे है। सिस्टम को पता लग जाएगा कि अनुवाद-योग्य पृष्ठ पर टैग्स कब जोड़े जाते हैं, और पृष्ठ पर उसे अनुवाद-योग्य चिह्नित करने की एक कड़ी दिखाई जाएगी। अगर आप, मान लीजिए, कोई टैग बंद करना भूल जाते हैं, यह शिकायत करेगा और आपको सहेजने से रोकेगा। अनुवाद-योग्य पृष्ठ को Special:PageTranslation पर 'चिह्नित करने के लिए तैयार' के रूप में सूचीबद्ध कर दिया जाएगा।

चिह्नित। टैग करने के बाद अनुवाद प्रबंधक पृष्ठ को अनुवाद के लिए चिह्नित कर सकता है। इंटरफ़ेस पृष्ठ अनुवाद उदाहरण में समझाया गया है। अनुवाद प्रबंधक की ज़िम्मेदारी यह सुनिश्चित करना है कि विभाजन समझ में आता है और टैग करना उचित है। इस बीच पृष्ठ को फिर से चिह्नित किया जा सकता है यदि यह इस बीच बदल गया है। नीचे देखें परिवर्तन कैसे करें जिससे न्यूनतम बाधाएं आती हैं। पृष्ठ का अंकन पृष्ठभूमि प्रक्रिया शुरू करता है जो मीडियाविकि नौकरी कतार का उपयोग करता है। यह प्रक्रिया प्रत्येक अनुवाद पृष्ठ पर जाती है और इसे पुन: उत्पन्न करती है: अनुवाद पृष्ठ टेम्पलेट में परिवर्तन प्रतिबिंबित होंगे और पुराने अनुवाद मूल स्रोत टेक्स्ट के साथ अस्थायी रूप से प्रतिस्थापित किए जाएंगे। इसके विपरीत, अनुवाद इंटरफ़ेस तुरंत अपडेट किया गया है।

परिवर्तन उपयोगकर्ता अनुवाद करने योग्य पेज स्रोत में परिवर्तन करना जारी रख सकते हैं। परिवर्तन स्रोत भाषा में पृष्ठ देखने वाले उपयोगकर्ताओं को दिखाई देंगे, लेकिन अनुवाद के लिए चिह्नित अनुवादित पृष्ठ के अंतिम संस्करण से निकाली गई अनुवाद इकाइयों के विरुद्ध अनुवाद किए गए हैं: अनुवाद पृष्ठ 100% तक रिपोर्ट किए गए हैं दिनांक अगर सभी अनुवाद इकाइयों का अनुवाद किया गया है, भले ही स्रोत पृष्ठ में नए बदलाव हों। स्रोत भाषा में अनुवाद करने योग्य पृष्ठ को देखते समय आप आसानी से देख सकते हैं कि शीर्ष पर एक नोटिस है जो कहता है कि आप इस पृष्ठ का अनुवाद कर सकते हैं और यदि कोई हो तो परिवर्तनों के लिंक भी हो सकते हैं।

अमान्यता यदि अनुवाद करने योग्य पेज स्रोत में परिवर्तन किए जाते हैं, तो अनुवाद प्रशासक को प्रत्येक खंड के लिए "" करने का विकल्प दिया जाएगा। यदि कोई अनुभाग अमान्य है, तो अनुवादित भाषाओं को उन अनुभागों के लिए गुलाबी पृष्ठभूमि रंग मिलेगा, और एक घड़ी आइकन अनुवाद इंटरफ़ेस में अनुवादकों को दिखाया जाएगा। यदि कोई अनुभाग अमान्य नहीं है, तो अनुवादित पृष्ठों के पाठकों को कोई भी परिवर्तन दिखाई नहीं देगा, और अनुवादकों को परिवर्तन देखने के लिए अनुवाद इंटरफ़ेस के भीतर अनुभाग की जांच करनी होगी।

स्रोत भाषा। स्रोत भाषा के भाषा कोड के साथ एक अनुवाद पृष्ठ भी है: इसमें पृष्ठ टैग से संबंधित अतिरिक्त टैग और अन्य मार्कअप शामिल नहीं हैं जिनका अनुवाद करने योग्य पृष्ठ स्रोत में उपयोग किया जाता है। यह पृष्ठ इंटरफ़ेस से लिंक नहीं है, लेकिन उदाहरण के लिए यह आसान है जब आप पृष्ठ को स्थानांतरित करना चाहते हैं (आमतौर पर अनुवाद करने योग्य टेम्पलेट्स के लिए) या इसे निर्यात करें। उदाहरण के लिए, आप जिस पृष्ठ पर हैं, वह Help:Extension:Translate/Page translation administration/en पर मार्कअप के बिना उपलब्ध है।

Changing the source language. The extension will normally assume that the translatable source page is in the wiki's default language. Administrators can change a specific page's language setting, using the Special:PageLanguage page, so that it can be used as a source page for translation. See Page content language for details.

Translation language. Translation pages may contain text in different languages if it is not fully translated. On translation pages, untranslated translation units will be tagged with appropriate language and text direction so that CSS rules are applied correctly. MediaWiki, however, does not currently allow setting the language for parsing other than at the page level. All magic words and parser functions use the translation target language, even if the surrounding text is not translated. This can create an unwanted mismatch for example when formatting numbers or dates. Some magic functions and parser tags allow setting the output language, in which case you can use magic word  that returns either the source language for untranslated units or the target language for translated units.

Closed translation requests. Some translatable pages have a content that is only interesting for a certain period of time. For example announcements and regular status updates, like the Wikimedia monthly highlights. You can keep those pages around with translations, but hide them from the translation interface. This does not prevent further translations to the pages, but it greatly reduces the chance that a user accidentally starts translating the page. Discouraging and its reversion are done from Special:PageTranslation.

Prioritizing languages. You can also define a list of languages that you specifically want translations into; leaving the language list empty is interpreted as all languages allowed. The page will behave like a discouraged page (see previous paragraph) for the languages not in the priority list and, when translating into them, translators will be given a notice. You can also prevent the translation in other languages, say if translations are actually used elsewhere and you won't be able to use them but in some languages.

Grouping. It is possible to group related pages together. These groups work like all the other message groups. They have their own statistics and contain all the messages of the subgroups: in this case translatable pages. This functionality is currently in Special:AggregateGroups. Aggregate message groups are collapsed by default in Special:LanguageStats in the group selector at Special:Translate.

Moving. You can move translatable pages as you would move any other page. When moving you can choose whether you want to move any non-translation subpages too. The move uses a background job to move the many related pages. While the move is in progress, it is not possible to translate the page. Completion is noted in the page translation log.

Deleting. Like move, deletion is accessed from the normal place. You can delete either the whole translatable page, or just one translation page, from the delete button on it. Deletion will also delete all the related translation unit pages. As in move, a background process will delete the pages over time and completion is noted in the page translation log. Deletion requires "delete" and "pagetranslation" permission, but individual translation unit pages can always be deleted with standard "delete".

Reverting. Similarly, reverting incorrect edits works as usual (including the rollback button): you only have to edit the affected translation unit and the translation page will be updated as well. To find the edit to the translation unit from the edit to the translation page, just click the "" link for the editor and look for an edit at a similar time.

Protecting. It is possible to protect the translatable page. Translation pages cannot be protected, nor does the protection of the translatable page extend to them. To prevent further edits to translations, you should add the source language as only priority language and disable translations to other languages, see prioritizing languages above. Together these two actions effectively prevent changes to both the source page and translation pages with its translation unit pages. It is possible to protect individual translation unit pages, though it is not advisable.

Removal from translation. It is also possible to unmark a page for translation. You can use Special:PageTranslation or follow the link in the top of translatable page to remove it from translation. This will remove any structure related to page translation, but leave all the existing pages in place, freely editable. This action is not recommended.

Language aware transclusion. It is possible to transclude a translatable page into another page as a template. In such a case, the translatable page will be loaded in the language of the source page if it has been translated to that language. If that translation does not exist, the translatable page will be loaded in the source language. This behavior of a translatable page is controlled by the Enable translation aware transclusion for this page option when marking the page for translation. New translatable pages will have this behavior turned on by default.

Anatomy of a translatable page
The translation of a translatable page will produce many pages, which all together compose the translatable page in the broadest sense: their title is determined by the title of the translatable :


 * - the source page
 * - the translation pages, plus a copy of the source page without markup
 * - all the translation unit pages

In addition to this, there are the translation page template and the sources of translation units, extracted from the source page and stored in the database. The system keeps track of which versions of the source page contain translation tags and which version of them have been marked for translation.

Every time a translation unit page is updated, the system will also regenerate the corresponding translation page. This will result in two edits. The translation unit page edit is hidden by default in recent changes and can be shown by choosing show translations from the translation filter. Any action other than editing (like deleting and moving) the translation unit pages will not trigger the regeneration of the corresponding translation page.

If you need the copy of the source page without markup, e.g. to be pasted in another wiki without Translate,


 * identify the source language code (for English, en ) and visit
 * click the "" button to reach an address like this and replace  with   in the address bar, press enter
 * the text will be displayed or saved.

Segmentation
General principles:


 * 1) All text intended for translation must be wrapped in  tags. There can be multiple pairs of tags in one page.
 * 2) Everything outside those tags will not change in any translation page. This static text, together with the placeholders which mark the place where the translation of each translation unit will be substituted, is called the translation page template.
 * 3) Too much markup in the text makes it difficult for translators to translate. Use more fine grained placing of  tags when there are lots of markup.
 * 4) The text inside  tags is split into translation units where there is one or more empty lines between them (two or more newlines).

Restrictions. The page translation feature places some restrictions on the text. There should not be any markup that spans over two or more translation units. In other words, each paragraph should be self-contained. This is currently not enforced in the software, but violating it will cause invalid rendering of the page, the severity depending on whether MediaWiki itself is able to fix the resulting HTML output or not.

Parsing order. Beware, the tags work differently from other tags, because they do not go through the parser. This should not cause problems usually, but may if you are trying something fancy. In more detail, they are parsed before any other tags like or, except for  which is recognized by the Translate extension.

Tag placing. If possible, try to put the tags on their own lines, with no empty lines between the content and the tags. Sometimes this is not possible, for example if you want to translate some content surrounded by the markup, but not the markup itself. This is fine too, for example:

To make this work, the extension has a simple whitespace handling: whitespace is preserved, except if an opening or closing  tag is the only thing on a line. In that case the newline after the opening tag or before the closing tag is eaten. This means that they don't cause extra space in the rendered version of the page.

Variables. It is possible to use variables similar to template variables. The syntax for this is (quotes are optional if the value contains no spaces or any of  ). For translators these will show up only as, and in translation pages will automatically be replaced by the value defined in the translatable page (so they are global "constants" across all its translation pages). Variables can be used to hide untranslatable content in the middle of a translation unit. It also works for things like numbers that need to be updated often. You can update the number in all translations by changing the number in the translatable page source and re-marking the page. You do not need to invalidate translations, because the number is not part of the translation unit pages.

Comma-separated values. For content such as Graph data, that needs to be parsed by the software as comma-separated values, you should separate the translation units between each comma, so that the translating editors don't use localized commas which will confuse the software.

Plain-text values. To prevent any kind of modification of the translation value, use  attribute like this:. By default outdated and untranslated values are modified in order to support highlighting and language tagging.

Markup examples
Below are listed some alternatives and suggested ways to handle different kinds of wiki markup.

{| class=wikitable
 * - style="visibility:collapse"
 * colspan="3" |
 *  Categories 
 * width=40% | Categories can be added in two ways: in the translation page template or in one of the translation units.
 * width=40% | Categories can be added in two ways: in the translation page template or in one of the translation units.

If you have the categories in the translation page template, all translations will end up in the same category.

If you have categories inside translation units, you should teach the users a naming scheme.

On the right we show two possible schemes which are independent of the technical means to adopt them. Translation by adding language suffix: Category:Cars/fi (recommended)


 * Category page name not translated (just like the page names).
 * One category for each language.
 * Page translation could be used for the category itself: the categories would be linked together and the headings would be translated (but not the name of the category in links and such).

 No translation : Category:Cars


 * All translations in same category (good if only few languages, bad if many).
 * Category name not translated (can be put as is in the translation template).
 *  Headings 
 * Headings can in principle be tied to the following paragraph, but it is better to have them separated with an empty line. This way someone can quickly translate the table of contents before going into the contents.
 * Headings can in principle be tied to the following paragraph, but it is better to have them separated with an empty line. This way someone can quickly translate the table of contents before going into the contents.

When tagging headings, it is important to include the heading markup inside the tags and insert a newline between the opening translate tag and the heading markup, or MediaWiki will no longer identify them properly. For example, section editing only works with the recommended mark-up given in the example. The markup also immediately gives translators a context: they are translating a heading.  Wrong:  (no newline after tag, heading out of translate tags) {{#tag:syntaxhighlight|

translateCulture/translate

 * lang="html"}}

 Recommended segmentation:  {{#tag:syntaxhighlight| {{^(}}translate{{)^}}

 *  Images 
 * Images that do contain language specific content like text should include the full image syntax in an unit. Other images can only tag the description with optional hint in message documentation of the page after it has been marked.

 *  Links 
 * Links can be included in the paragraph they are inside. This allows changing the link label, but also changing the link target to a localized version if one exists.
 * Links can be included in the paragraph they are inside. This allows changing the link label, but also changing the link target to a localized version if one exists.

If the target page is (or should be) also translatable, you should link to it by prepending  to its title. Only the link label will need to be translated, because this automatically redirects users to the translation page in their own interface language, as selected for instance via the UniversalLanguageSelector. However, to achieve a constant behavior the syntax must be used for all links.

Because headings are translated, you cannot rely on the automatically generated id's for headings. You can add your own anchors. To have them outside of the translation template you need to break up the page into multiple tag pairs around each heading you want to have an anchor to.  Internal links: 

 Links to translatable pages: 

 External links: 

 Links within a page:  {{#tag:syntaxhighlight| span id=culture{{^(}}/span{{)^}} {{^(}}translate{{)^}}

Do so only if the items are sufficiently independent to be translated separately in all languages: don't create "lego messages". For instance, you must avoid to split a single sentence in multiple units, or to separate logically dependent parts which may affect each other (with regard to punctuation or style of the list, for instance). To split a list, use -tags for each item without including leading asterisks/hashes/semicolons. Do not insert blank lines as this will break the HTML output.

 * With numbers and other non-linguistic elements you may want to pull the actual number out of translation and make it a variable. This has multiple benefits:


 * You can update the number without invalidating translations.
 * Translation memory can work better when the changing number is ignored.

Note that this prevents the translators from localising the number by doing currency conversion. The  call makes sure the number is formatted correctly in the target language.


 *  Templates 
 * Templates have varying functions and purposes, so the best solution depends on what the template is for. If the template is not a part of longer paragraph, it should be left out, unless it has parameters that need to be translated. If the template has no linguistic content itself, you don't need to do anything for the template itself.
 * For an example of templates translated with page translation, see . To use this template, you need to have another template similar to Translatable navigation template, because you cannot include the template by  anymore. This is not yet provided by the Translate extension itself, but that is in the plans.

To use this template, you need to have another template similar to Translatable navigation template, because you cannot include the template by  anymore. This is not yet provided by the Translate extension itself, but that is in the plans.

Another way is to use the unstructured element translation to translate the template, but then the language of the template will follow the user's interface language, not the language of the page they are viewing.

Without the magic word, untranslated text on a Finnish translation page would render as:

Changing the source text
General principles:


 * Avoid changes
 * Make the changes as isolated as possible
 * Do not add translation unit markers yourself

Unit markers. When page is marked for translation, the system will update the translatable page source and add unique identifiers, called "unit markers", for each translation unit. See example below. An example of a unit marker is. These unit markers are crucial for the system, which uses them to track changes to each translation unit. You should never add unit markers yourself. The unit markers are always on the line before the unit; or, if it starts with a heading, after the first heading on the same line. The different placement for headings is needed to keep section editing working as expected.

{{#tag:syntaxhighlight| {{^(}}translate{{)^}}

Birds
!--T:1-- Birds are animals which....

!--T:2-- Birds can fly and... /translate
 * lang=html}}

Changing unit text. Changing is the most common operation for translation units. You can fix spelling mistakes, correct grammar or do other changes to the unit. When re-marking the page for translation, you will see the difference in the unit text. The same difference is also shown to translators when they update their translations. For simple spelling fixes and other cases where you don't want the existing translations to be highlighted on the translated pages, you can avoid invalidating them: translators will still see the difference if they ever update the translation for any reason.

Adding new text. You can freely add new text inside tags. Make sure that there is one empty line between adjacent units, so that the system will see it as a new unit. You can also add tags around the new text, if it is not inside existing  tags. Again, do not add unit markers yourself, the system will do it.

Deleting text. You can delete whole units. If you do so, also remove the unit marker.

Splitting units. You can split existing units by adding an empty line in the middle of a unit, or by placing tags so that they split the unit. You can either keep the unit marker with the first unit or remove it altogether. In the first case, translators see the old text when updating the old translation. If you removed the unit marker, both units will behave as if no translation ever existed, after the page is re-marked for translation.

Merging units. If you merge units, you have to remove at least all but one unit marker.

Moving units. You can move units around without invalidating translations: just move the unit marker together with the rest of the unit.

Before marking the new version of the page for translation, ensure that the best practices are followed, especially that translators get a new translation unit if the content has changed. Also make sure that there are no unnecessary changes to prevent wasting translators time. If the source page is getting many changes, it may be worthwhile to wait for it to stabilize, and push the work for translators only after that.

Unused unit translations are not deleted automatically, but that should not cause trouble.

Migrating to page translation
If you have been translating pages before using the page translation system, you might want to migrate the pages to the new system, at least the ones you expect to have new translations and want statistics for. You will probably have existing templates for language switching and maybe different page naming conventions.

You can start migration by cleaning up, tagging and marking the source page. You can keep the existing language-switching templates while you migrate the old translations. If your pages follow the language code subpages naming convention, they will be replaced with the source text after marking the source page for translation, but you'll still be able to access translations from history.

This manual task has been partly automated by Special:PageMigration, which shows the source and target units besides each other and allows the user to adjust the units by providing a set of features mentioned later in this page.

How to use?
500px| Screenshot showing an example use of Special:PageMigration for "Help:Special pages" as page name and "fr" as language code.
 * 1) Go to Special:PageMigration
 * 2) Enter the title of the page and the language code. For example, "Help:Special pages" & "fr"
 * 3) The source text which was divided into units by Translate and the imported translations will be shown besides each other with some initial alignment.
 * 4) Use the actions available for each unit to manually do the remaining alignment
 * 5) As translated units are editable, do required manual improvements (for add translation variables, fix links and markup, etc.)
 * 6) Click on the "" button. This will create pages under the Translations namespace of the form  . The old translations have been imported into Translate.
 * 7) Else, if you wish to abort the importing, click on the 'Cancel' button.

Actions available
Each row consisting of source and target unit has a set of action icons. They are used as follows:
 * 1) Add: Clicking on this action icon adds a new empty unit below the current one. Use this feature if you want to split the current unit and need a unit below.
 * 2) Swap: Clicking on this action icon swaps the content of the current unit with the unit below it. You can use this feature when the units get aligned improperly due to different ordering of sections. Or when you need to drag a unit below or above. In either case, remember it swaps with the unit below and does not create any additional units.
 * 3) Delete: Clicking on this action icon completely removes the corresponding target unit from the page and shifts the remaining target units up by one unit. Use this to remove unwanted content like code or imported translations which are present completely in the source language. Note: this irrevocable action (in the current session).

Troubleshooting

 * 1) If you mark a page for translation and immediately go to the special page and try to import translations, you may get an error message like "". This is because FuzzyBot didn't fuzzy the messages on the old page yet: the tool won't find an edit by FuzzyBot on the translation page. In this case, simply wait for FuzzyBot to do its job. Once an edit is seen, you can proceed with the imports.
 * 2) Please wait for some time after pressing the "" button. While the button background remains gray, there is an ongoing process of importing non-empty units. Once the button becomes colored again, the import is completed.

Tips

 * 1) Migration will be easier if you first (before the mark to translation) check whether existing translations are similar to the original English text, and manually edit the structure of pages: break paragraphs and lists, add the missing headings (even if empty).
 * 2) Will be useful to check the result in the core translation interface - some of the units may be immediately marked as obsolete because of errors markup or if not all of the translation variables was added.
 * 3) Translation of the page title will have to be added manually. If you do not know very well the language of the imported page, you can try to find the translation of the page title among the "links here" or sometimes in redirects.
