/* HotCat V2.34 (Copied from https://commons.wikimedia.org/wiki/MediaWiki:Gadget-HotCat.js and revised slightly for Miraheze)

Ajax-based simple Category manager. Allows adding/removing/changing categories on a page view. Supports multiple category changes, as well as redirect and disambiguation resolution. Also plugs into the upload form. Search engines to use for the suggestion list are configurable, and can be selected interactively.

/* This code is MW version safe. It should run on any MediaWiki installation >= MW 1.15. Note that HotCat is supposed to run with or without jQuery, and also on older installations that do not yet have window.mw. If you use any of these newer features, make sure you qualify them by checking whether they exist at all, and by providing some meaningful fallback implementation if not. To start itself, HotCat uses jQuery(document).ready. If it doesn't exist, HotCat won't start. /* jshint ignore:start */ // This old code uses too many coding conventions incompatible with jshint.

This is browser/OS/IME dependent, but basically there are two mechanisms: // - Modern (DOM Level 3) browsers use compositionstart/compositionend events to signal composition; if the //  composition is not canceled, there'll be a textInput event following. During a composition key events are //  either all suppressed (FF/Gecko), or otherwise have keyDown === IME for all keys (Webkit). //  - Webkit sends a textInput followed by keyDown === IME and a keyUp with the key that ended composition. //  - Gecko doesn't send textInput but just a keyUp with the key that ended composition, without sending keyDown //    first. Gecko doesn't send any keydown while IME is active. // - Older browsers signal composition by keyDown === IME for the first and subsequent keys for a composition. The //  first keyDown !== IME is certainly after the end of the composition. Typically, composition end can also be //  detected by a keyDown IME with a keyUp of space, tab, escape, or return.
