หากคุณต้องการที่จะลองโปรแกรม visual editor โดยไม่ต้องแก้ไขบทความ นี่คือหน้าที่คุณสามารถทดสอบได้อย่างเสรี คุณไม่จำเป็นต้องมีบัญชีการใช้ visual editor ในหน้านั้น

การเปิด visual editor

การแก้ไขหน้าเว็บโดยใช้ visual editor คลิกที่แท็บ "แก้ไข" ที่ด้านบนของหน้า การเปิดหน้าขึ้นมาเพื่อแก้ไขอาจใช้เวลาหลายวินาทีหรือนานกว่านั้นถ้าหน้าที่ต้องการแก้ไขมีเนื้อหามาก คลิกที่แท็บ "แก้ไขต้นฉบับ" จะเปิดหน้าต่างตัวแก้ไขแบบดั้งเดิม
หรือคุณอาจเปิด visual editor โดยการคลิกที่ลิงก์ "แก้ไข" ในแต่ละส่วน

เริ่มต้นใช้งาน: แถบเครื่องมือของ visual editor

แถบเครื่องมือ VisualEditor จะปรากฏขึ้นเมื่อขึ้นเริ่มแก้ไขผ่าน VisualEditor โดยจะประกอบไปด้วยไอคอนที่เราคุ้นเคยกันเช่น
	เลิกทำและทำซ้ำ การแก้ไขที่คุณสร้างขึ้น
	Headings pull-down menu: allows you to change how the paragraph is formatted. To change the style of a paragraph, put your cursor in the paragraph and select an item in this menu (you don't have to highlight any text). Section titles are formatted "หัวเรื่อง", and subsections are "หัวเรื่องรอง 1", "หัวเรื่องรอง 2", and so on. The normal format for text is "ย่อหน้า".
	Formatting: Pressing the "A" opens a menu. The "ตัวเส้นหนา" item (B) bolds the selected text. The "ตัวเอน" item (I) italicizes the selected text. The "ตัวยก" item (x2) causes the selected text to appear smaller than surrounding text and to be slightly higher than the surrounding text. The "ตัวห้อย" item (x2) causes the selected text to appear smaller than surrounding text and to be slightly lower than the surrounding text. The "ขีดทับ" item (S) adds a solid bar through the selected text. The "รหัสคอมพิวเตอร์" item (a set of curly brackets: {}) changes the font of the selected text to a monospaced font, which sets it apart from surrounding (proportionally spaced) text. The "เส้นใต้" item (U) adds a solid line beneath the selected text. The "ภาษา" item (文A) allows you to label the language (for example, Japanese) and direction (for example, right-to-left) of the selected text. The final item (), called "ลบ", removes all character formatting from the selected text, including links. If you have not selected any text, then when you press the "A" to open the menu, and then select an item, that formatting will apply to the text that you start typing, from wherever your cursor is located.
	Linking tool: The chain icon is the linking tool. Pressing on it (usually after selecting some text) opens the link dialog.
	อ้างอิง menu: The "อ้างอิง" menu is used to add inline citations (also called "footnotes" or "references"). All projects have access to basic reference formatting and the ability to reuse citations by using this menu. It also gives users quick access to local citation templates, if these are enabled on their wiki. (Instructions for adding local citation templates to the อ้างอิง menu at a specific wiki are available at VisualEditor/Citation tool .)
	⧼citoid-citefromidtool-title⧽ button: If the citoid service is enabled on your wiki, then you will see a ⧼citoid-citefromidtool-title⧽ button instead of a อ้างอิง menu. The citoid service tries to fill out citation templates automatically.
	รายชื่อและย่อหน้า: ไอคอนสองอันแรกใช้สร้างรายชื่อในรูปแบบของตัวเลขหรือแบบจุดตามลำดับ อีกสองตัวใช้เพิ่มหรือลดระดับของย่อหน้าของเนื้อหา
	สื่อ, อ้างอิง และ แม่แบบ: ไอคอนแต่ละไอคอนเปิดหน้าต่างดังนี้: ไอคอน "สื่อ" รูปภูเขา เปิดตัวจัดการสื่อ. The "Template" icon (a puzzle piece) allows you to edit templates. The "Table" item allows you to insert a table. The "ความเห็น" item (a speech balloon) allows you to insert comments that are not visible to readers; these comments can be seen only when in edit mode, where they are indicated by an exclamation mark icon. In edit mode, pressing on the exclamation mark icon allows you to edit or delete the comment. The "Hieroglyphs" icon (an ankh symbol - ☥) allows you to enter the hieroglyphics inserter. (See below.) The "Code block" item allows you to insert code. The "Musical notation" item allows you to insert a musical notation. The "Gallery" icon (a set of photos) allows you to insert a gallery to the page. The "สูตรคณิตศาสตร์" icon (Σ) opens the formula inserter dialog. The "Graph" item allows you to insert a graph. The "Your signature" item allows you to insert a signature that you use on the project. It will be greyed out (not selectable) when you are editing a type of page (a "namespace"), such as an article, where signatures should not be inserted. ไอคอน รายการอ้างอิง" รูปหนังสือสามเล่มเปิดหน้าต่างแสดงรายการอ้างอิง
Special character insertion: The "อักขระพิเศษ" (Ω) icon is next to the "แทรก" menu. When pressed, it displays a dialog showing many special characters. By pressing on a specific character, you place it into the text. These special characters include some standard symbols, diacritics, and mathematical symbols. (This list may be customized locally. See VisualEditor/Special characters for instructions.)

	The Edit notices button displays any notices for the page.
	The ตัวเลือกหน้า menu is to the left of the เผยแพร่การเปลี่ยนแปลง button and the Switch editor menu. On this menu there is a button to open an Options dialog with the following (left side) tabs: หมวดหมู่ allows you to add categories to this page and to adjust how the page is sorted, when displayed within a category by setting a different index to sort with. การตั้งค่าหน้า allows you to make the page a redirect and adjust options of this redirect, to adjust settings regarding the displaying of the Table of Contents, to disable the edit links next to each heading, and to define the page as a disambiguation page. Advanced settings allows you to adjust the settings regarding indexation of the page by search engines, showing a tab to add a new section, and the displayed title. Languages which shows a list of pages in other languages that are linked to that page. Templates used shows a list of links to each template used on this page. The tabs of the Options dialog are also displayed in the ตัวเลือกหน้า menu and can be opened by clicking on it. Furthermore the ตัวเลือกหน้า menu contains the button View as right-to-left and the button Find and replace which opens a dialog where you can insert characters, terms or Regular expressions you are searching for and those to replace them with, together with several buttons for options.
	The switch to source editing button is next to the เผยแพร่การเปลี่ยนแปลง button. It allows you to switch to the wikitext editor.

การบันทึกการแก้ไข

เมื่อคุณแก้ไขเสร็จแล้ว คลิกปุ่ม "เผยแพร่การเปลี่ยนแปลง" สีเขียวในแถบเครื่องมือ ปุ่มสีเขียวนี้จะคลิกไม่ได้หากไม่มีการแก้ไขเกิดขึ้น To cancel all your editing changes, close your browser window, or press the "อ่าน" tab above the edit toolbar.
การกดปุ่ม"⧼Visualeditor-toolbar-savedialog⧽"สีเขียวนี้ จะเปิดหน้าต่างเล็กๆ สำหรับให้คุณเขียนสรุปการกระทำของคุณ ตั้งให้เป็นการแก้ไขเล็กน้อย และเลือกที่จะเฝ้าดูการแก้ไขเพิ่มเติมของหน้านั้นๆ ตัวเลขบอกถึงช่องว่างที่เหลือในที่สรุปการแก้ไข คุณยังสามารถตรวจสอบการแก้ไขก่อนบันทึกเพื่อความมั่นใจว่ามันเป็นไปตามที่คุณต้องการ The "แก้ไขต่อ" button returns you to the page you were editing. You can publish all of your changes later.

การแก้ไขลิงก์

	คุณสามารถเพิ่มลิงก์ผ่านทางไอคอน "ลิงก์" (รูปโซ่)ในแถบเครื่องมือหรือผ่านทางลัด Ctrl+K (หรือ ⌘ Command+K บนแมค). If you select (highlight) text and then press the "ลิงก์" button, that text will be used in creating the link. For a link that involves only one word, you can either select that word or just put the cursor within that word.
	ไม่ว่าคุณจะกดปุ่มในแถบเครื่องมือหรือผ่านทางลัด หน้าต่างจะปรากฏให้คุณพิมพ์ลิงก์ที่คุณต้องการเชื่อม VisualEditor จะพยายามช่วยคุณหาลิงก์ภายใน (ลิงก์หน้าอื่นๆ ของวิกิพีเดีย) โดยการค้นหาหน้าที่อาจใช่ทันทีที่คุณเริ่มพิมพ์ The link tool will try to help with internal links by searching for likely matches.
	หลังจากคุณพิมพ์หรือเลือกลิงก์เสร็จ คุณอาจกด↵ Enterหรือกดข้างนอกหน้าต่างหรือกดไอคอนปิด (<)ลิงก์จะปรากฏในหน้า VisualEditor แต่จะยังไม่ถูกบันทึกจนกว่าคุณจะทำเช่นนั้น
	การลิงก์ไปยังหน้าเว็บนอกวิกิพีเดียจะใช้กระบวนการเดียวกัน เพียงแค่ใส่ลิงก์เข้าไปในช่องจากนั้นมันจะถูกเพิ่มเข้าไปในฐานะลิงก์ภายนอก
	External links without labels look like this: [1]. You can add these by placing your cursor away from any word (e.g., after a space). Open the link tool by pressing on the button or pressing the shortcut keys. Type the URL in the box, and press the "สำเร็จ" button to insert the link.
	ในการแก้ไขหรือลบลิงก์ที่มีอยู่แล้ว คลิกที่ลิงก์นั้นแล้วคลิกไอคอนลิงก์ที่จะปรากฏขึ้นใกล้ๆ หรือคุณอาจคลิกไอคอนในแถบเครื่องมือ หรือใช้ทางลัดบนคีย์บอร์ด Ctrl+K ก็ได้ When a link is selected, it appears as blue framed. In the link editing dialog, you can then change where the link goes. You can also remove the link entirely by pressing the "ลบออก" button in the upper right corner of the dialog. You can also open the link's target in another window by pressing on the copy of the link in the dialog box. (You might want do this to check if an external link is valid.) If you want to exit the link label (the text displayed as a link) or continue to write after this link, you can press →: Pressing it once will escape the link editing dialog and put your cursor at the end of the element linked (blue framed, to edit this element) Pressing it twice will put the cursor after the element linked, ready to type the rest of your text. To edit the link label of an existing link, press within the link label and type the new one. But if you want to replace the entire label, please note: If you have selected (highlighted) the entire link label, the link will be deleted by typing any key. You may link it from start. To keep the link directly, you may press within that link label, use backspace and delete key without pressing it once more than necessary, and a narrow blue link area will remain there. Now you may type in the new label for the kept link. You can also link to categories, files and more.

การแก้ไขแหล่งอ้างอิง

For further information, see Help using citation templates or Help using citoid's Cite button

Determining which system is in place
Your wiki may use one of three footnote systems. The one shown on the right is the simplest system, where the "อ้างอิง" menu does not include any citation templates. If your wiki uses this system, then everything you need to know about footnotes is on this page.
The second system has the same type of "อ้างอิง" menu, but with several popular citation templates set up for quick access. If your wiki uses this system, then you will find more details at Help:VisualEditor/User guide/Citations-Templates
In the third system, you again start by pressing the Cite button. Then a dialog box opens, which includes an automatic citation process using the citoid service. If your wiki uses this system, you will find more details at Help:VisualEditor/User guide/Citations-Full
แก้ไขแหล่งอ้างอิงที่มีอยู่
To edit an existing reference, press on it where it appears in the text (usually as a bracketed number). You will see either a "แหล่งอ้างอิง" icon (bookmark) or an icon (and name) for the template that was used to create this reference. In either case, pressing on the "Edit" button will open a dialog where you can edit the reference.
For the "แหล่งอ้างอิง" icon, pressing "Edit" opens the Reference dialog. To start changing the reference information, press on it. หลายวิกิใช้แม่แบบในการจัดรูปแบบแหล่งอ้างอิงในมาตรฐานที่แตกต่างกัน คุณจะสังเกตได้เมื่อคุณแก้ไขแหล่งอ้างอิงที่มีอยู่และพบว่าเนื้อหาข้อความอ้างอิงเปลี่ยนเป็นสีฟ้าเมื่อคุณเลือกมัน If a template was used and you press on the reference information, then the Template icon (puzzle piece) will appear with some information. Press on the "edit" button to edit the content of the template in the template mini-editor dialog.
If what appears when you press on a reference is an icon for a standard template for citations (an example is at right), then pressing "Edit" will open the template mini-editor dialog.
Inside the template mini-editor, you can add or remove types of information or change current content. Only fields (template parameters) that have content will show, initially. To add fields, press on "เพิ่มข้อมูลอีก" at the bottom of the mini-editor.
คลิกที่ "ใช้การเปลี่ยนแปลง" เมื่อคุณเสร็จแล้ว
การใช้ซ้ำแหล่งอ้างอิงที่มีอยู่
If the page already contains a citation that applies to the text you want to source, then you can choose to re-use that existing citation. To re-use an existing reference, place your cursor in the body of the text where you want to add a new reference (number) for that citation. Then press on the "Re-use reference" item from the "อ้างอิง" menu. (Note: If your wiki has the third footnote system described above, you'll see a "Re-use" tab, in a dialog, instead of a "Re-use" item on the "อ้างอิง" menu.)
In the อ้างอิง dialog, look at the list for the reference you want to reuse, and select it. If there are many references, you can use the search box (labeled "ค้นหาภายในแหล่งอ้างอิงปัจจุบัน") to list only those references that include certain text.
Adding a new reference
To add a citation using the "อ้างอิง" menu, place your cursor where you want to add it in the text. Then select the appropriate citation type in the menu.
Using the "Basic" citation
Shown here is what you will see if you select the basic references item. In the Reference editor, you can add your citation, including formatting. You can make the reference belong to a given group, although normally this is left blank. (This option is used to display groups of references with the "รายการอ้างอิง" tool.)
In the Reference dialog, if you want to include a citation template, or any other template, in your new reference, press the Template icon (puzzle piece) in the "แทรก" toolbar menu within the Reference editor.
Then, look for the template you want to use, add it and edit it as you would any other template. (See the Editing templates section, below, if you need more information about templates.) After you are done editing your new template, press on "ใช้การเปลี่ยนแปลง" to return to the Reference editor, and "ใช้การเปลี่ยนแปลง" again to return to the page you are editing.
If there isn't already a list of references on the page (for example, if you are adding the first reference for the page), you need to specify where the list of references, and their text, will be displayed to the reader. Place the cursor where you want to display the references list (usually at the bottom of the page), open the "แทรก" menu and press the "รายการอ้างอิง" icon (three books).
If you are using several groups of references, which is relatively rare, you can specify the group in this dialog. Only the references that belong to that group will be displayed on the page at the location where you are placing the group. The final step in the References list dialog is to press "แทรก".
Using standard cite templates
Your local wiki may have added extra citation templates to the "อ้างอิง" menu. If so, you have quick access to the most-used citation templates for your wiki. (Instructions for adding extra citation templates to your local wiki are available at VisualEditor/Citation tool .)
Pressing on a template icon such as "Cite book" will take you into the template mini-editor for that template. Important information fields may be marked with an asterisk. While the most common fields will be shown, not all of them are required.
To add more parameters, scroll down in the template mini-editor and press on the "เพิ่มข้อมูลอีก" option. Press on "แทรก" when you are done.

Editing images and other media files

Editing images
การเพิ่มภาพใหม่ (หรือไฟล์สื่ออื่นๆ) ลงในหน้า คลิกที่ไอคอน "Media" (รูปภูเขา) ในแถบเครื่องมือ
การคลิกไอคอน "สื่อ" จะเปิดหน้าต่างสำหรับค้นหาไฟล์สื่อจากวิกิมีเดียคอมมอนส์ที่เกี่ยวข้องกับหน้าที่คุณแก้ไขอยู่ คุณอาจหาไฟล์สื่ออื่นๆ โดยการเปลี่ยนข้อความในกล่องค้นหา คลิกที่รูปย่อเพื่อเลือกไฟล์ This places the image onto the page you are editing.
After the image you selected is inserted into the page, another dialog will open. This dialog allows you to add and edit the caption of the image. The caption can contain formatting and links.
The media dialog also allows you to add alternative text captions, to help users who use screen readers, or who have disabled image display.
You can also set various parameters for the image in the "การตั้งค่าขั้นสูง" window. These include the alignment, the type, and size of the image.
เมื่อคุณเสร็จแล้ว คลิก "ใช้การเปลี่ยนแปลง" เพื่อปิดหน้าต่างและย้อนกลับไปสู่ตัวแก้ไขหน้า
For an existing image, you can add or edit a caption or other settings by pressing on the image, then pressing on the "สื่อ" icon that appears below the picture. You can resize an existing image by pressing on it, then moving the resize icon (the two-headed arrow on one or both bottom corners). You can also drag and drop an image to a place higher or lower on the page.

Uploading images

You can upload images from a tab in the media dialog, or by dragging and dropping a file into the editor, or by pasting an image from your clipboard.
Press the "Upload" tab and select an image from your computer. You can type the file name, or drag an image into the box. If you dragged and dropped an image directly into the editor, or pasted one from your clipboard, this tab will open automatically.
You need to describe the image and add categories to it so that other people can find it.
The image will be inserted into the page when you are done.

Editing media galleries

To add a new gallery, press the "Gallery" icon (a set of photos) on the "แทรก" menu. (If you don't see this icon on that menu, then your local wiki has decided to delay implementing this functionality in the visual editor.)
To edit an existing gallery in the visual editor, press that gallery. Then, near the bottom of the gallery, press the gallery icon (a set of photos). This brings up the gallery editor, with the full list of images included in the gallery.
The gallery editor is currently a simple box that allows you to edit existing galleries using wikitext markup. To add a new image to an existing gallery, type the file name, followed by a bar (|) and the caption for that image. You must put each image in the gallery on its own line. You can also edit this list to remove or rearrange images or to change captions. When you press the "สำเร็จ" button, you will exit the gallery editor. You should then see your changes, with the gallery as it will now appear to readers. Remember that exiting the gallery editor does not publish your changes. As with other changes made using the visual editor, you must publish the entire page in order to publish your work.

Editing templates

Starting

To add a new template to a page, place your cursor where you want the template to be inserted, and press on the "Template" icon (puzzle piece) in the "แทรก" menu.
Start typing the name of the template you want to insert. When you see it on the list, press on its name. Then press "เพิ่มแม่แบบ".
You can also edit a template that is already on the page. When you press on the template to select it, it turns blue, and a box appears with an "Template" icon (puzzle piece). Then press on the "แก้ไข" link.
Some templates are not visible to someone reading a page. In the visual editor, such hidden templates are shown as puzzle icons. The name of the template will be shown next to the puzzle icon.
When you select the icon, the context menu is displayed, and you can edit the template.
Template parameters
When you add a new template or open an existing one, the "ใช้แม่แบบ" dialog is shown. The contents depends upon whether the template has been documented using the new TemplateData system or not.
The template shown here has no TemplateData set up for it. The dialog therefore provides a link to documentation for the template. By visiting the documentation you should be able to figure out if the template has any parameters (fields), and what goes in each field. Use numbers as the name for each nameless parameter. The first un-named parameter is named 1, the second is named 2, and so forth.
If a template has been updated to contain TemplateData information, then the dialog will show a list of individual (named) parameters.
For an existing template, you can edit the parameters shown in the dialog, and you can add parameters by pressing "เพิ่มข้อมูลอีก", at the very bottom of the dialog.
When a template embeds other templates, these sub-templates will appear inside the parameters that display them. They can be edited or removed inside the parameter field. New sub-templates are added by following the steps for adding a parameter. You may need to check the template documentation to make sure that the sub-template is supported. Nested templates can currently be edited as wikitext only, without the facility offered by VisualEditor (see phab:T52182).
Finishing
When you have finished editing a template, press "ใช้การเปลี่ยนแปลง" to close the dialog and return to editing the main page.
Substituting templates
When a template must be substituted, type subst: (colon included) before the template's name. Autocompletion doesn't work with subst:. If you want to use autocompletion, first find the template you are looking for, and then add subst: in front of the template name. Then, press the blue "เพิ่มแม่แบบ" button. Add any parameters as usual and press "แทรก".
You will see the template expand on the page after you press "ใช้การเปลี่ยนแปลง".

Editing lists

	You can use the visual editor to create lists, or to change the format of an existing list. There are two types of lists: unordered (bullet) and ordered (numbered). To start a new list, just press on one of the two menu items shown here. Or, if you already have typed the list (on separate lines), select (highlight) the list you have typed, then press on one of the menu items.
	Shown here are examples of the two types of lists: unordered (bullet) and ordered (numbered).
	If you want to change the indentation level of part of an existing list, select the part of the list that you want to change.
	Then use the menu, or press the Tab key. (The Tab key increases indentation; use the shift key plus the Tab key to decrease indentation)
	Here is the result of increased indentation.
	You can even mix ordered (numbered) and unordered (bullet) lists, if the list items have different indentations.

Editing tables

	You can use the visual editor to insert and change tables. You can even import a table by dragging a comma-separated value (.csv) file from your computer into the main editing window.
When you press on "Table", in the "แทรก" menu, the visual editor inserts a blank four-by-four table. Now the "Table" menu is available. From that menu, you can add a caption to the top of the table.
To select a cell, press it once.
To edit the contents of the cell (for example, to add content or to correct a spelling error), double press in the cell. Or you can select the cell and then press Return. To end your editing of a cell, just press elsewhere.
	You can add or delete a column or a row.
You can merge cells: Select them, then from the Table menu, press on "Merge cells".
If you merge cells, only the text in one cell is kept; any text in the other cells is deleted when you merge the cells. If you decide that you wanted some or all of the text that was deleted, use the Undo button, move or copy the text you want, then merge the cells again.
You can also split cells that were previously merged. All the content that was in the merged cell will remain in the first cell when you do the split. You can then cut and paste text to other cells, if you want.

Editing categories

	To edit categories, on the "ตัวเลือกหน้า" menu, press the "หมวดหมู่" item.
	Pressing on "หมวดหมู่" opens a dialog that lists existing categories and allows you to add new ones, and to delete existing categories. You also have the option of setting or changing the general (default) sorting key, which determines where the page appears when listed with other pages in the same category. For example, the default sorting key for the article "George Washington" is "Washington, George". In the category "Presidents of the United States", the article is listed under the letter "W", not the letter "G".
	To add a category for a page, type the name of the category into the field "เพิ่มหมวดหมู่". As you type, the visual editor will search for possible matching, existing categories. You can either select an existing category, or you can add a category that doesn't yet have its own category page. (Until that category page is created, your new category will show as a red link after you publish all your editing changes.)
	To remove an existing category, press on it and press on the "ลบออก" icon (trash can) in the dialog that opens. Pressing on a category also allows you to specify a sorting key for that specific category. Such a sorting key overrides the default sorting key.
	Press "ใช้การเปลี่ยนแปลง" when you are done editing categories to return to the page editor.

Editing page settings

	To edit a page's settings, press to open the "ตัวเลือกหน้า" menu, in the toolbar, and select the "การตั้งค่าหน้า" button.
	The "การตั้งค่าหน้า" button opens a dialog that shows several options.
	You can make a page a redirect to another page by checking the "Redirect this page to" checkbox, and then typing the name of the page to which you want to send the reader who tries to go to the page that you are editing. At the bottom is the option to prevent page renames from updating this redirect. This is very rarely used.
	You can change whether the page shows a Table of Contents by selecting one of these three buttons. The default option is "If needed", which shows a Table of Contents if there are three or more headings.
	You can make a page not show edit links next to each section header by checking this checkbox.
	Press "ใช้การเปลี่ยนแปลง" when you are done editing the ตัวเลือกหน้า to return to the page editor.

Editing maps

You can add and change maps. See Help:VisualEditor/Maps .

Editing mathematical formulae

To add a new mathematical formula to the page, place your cursor where you want it to be inserted, and press on the "สูตรคณิตศาสตร์" icon ("Σ") in the "แทรก" menu on the toolbar.
A window will open in which you can type the formula, using LaTeX syntax. the visual editor will update the formula as you type it, so you can see how it will look as you make changes. Once you are happy with the formula, press the "แทรก" button.
To edit an existing mathematical formula on the page, press on it and then press on the "Σ" icon that appears. This will open up the formula window, where you make changes.
Mathematical formulae can be placed inline or centered as a block.

Editing musical scores

To add a new musical notation to a page, place your cursor where you want the musical notation to be inserted. Then, from the "Insert" menu on the toolbar, press the "Musical notation" option. To edit an existing musical notation on the page, double press on it.
This will open the "Musical notation" dialog. Here the notation can be edited by scale, either in ABC or in Lilypond format. You can also link the notation to an audio or MIDI file. Once you are finished, press the "Done" button to close the dialog and publish your changes.

Editing poems and other special items

Some items, such as association lists and poems, are not yet fully supported by the visual editor.
In most cases, the existing items can be edited, but new ones cannot be inserted in the visual editor. Until they are fully supported, you can copy an existing one from another page, or edit the source wikitext directly.

Switching between the visual and wikitext editors

To switch from the visual editor to the wikitext editor, press the [[ ]] button on the far right of the toolbar.
If you've done any editing, you'll be asked whether you want to keep your changes. Normally you'll press on "Keep changes".
You'll see a diff. (If you pressed on "Discard changes", you'll just see wikitext, ready to edit with the wikitext editor.) Scroll down, and you'll see the wikitext editing area.
You can also switch from the wikitext editor to the visual editor. To do that, press the pencil icon on the far right of the toolbar.
After you press the pencil icon, if you've done any editing you'll be asked whether you want to keep your changes. If you press "Keep changes", you'll go to the visual editor. If you press "Discard changes", you'll be asked to confirm that is what you want to do (press on "Leave Page" to confirm) before the visual editor will start.

ทางลัดบนคีย์บอร์ด

Many editors are used to entering wikitext directly, especially bold, italics and wikilinks. Keyboard shortcuts allow to quickly insert similar formatting without having to use toolbar items. Here are the common general shortcuts in the visual editor:

PC shortcut	Action	Mac shortcut
Ctrl+B	ตัวหนา	⌘ Cmd+B
Ctrl+I	ตัวเอียง	⌘ Cmd+I
Ctrl+K	เพิ่มลิงก์	⌘ Cmd+K
Ctrl+X	ตัด	⌘ Cmd+X
