MediaWiki allows you to skip to a particular point in a category by using the URL. For example, https://en.wiktionary.org/w/index.php?title=Category:English_lemmas&pagefrom=bear skips to the word "bear" in te category. It would be incredibly useful (vital even, for a dictionary) to be able to do this more easily. Could a new inputbox type be added that lets you fill in the term to skip to in a category?

That would probably be easier to do as a JavaScript gadget, so it's available on all category pages without the need to add an input box manually on every page.
