ChatWork チャット入力支援ツール is an unofficial Chrome extension created by tech vein, Inc. It enhances the ChatWork chat input field with convenient features. The extension adds shortcuts for easy input of [code], [info], [hr], and shortens the display of multiple recipients from "[To:0000]Aさん [To:0001]Bさん" to "[To:To:0001]".

The recent updates include support for the latest ChatWork site version, the addition of a feature to select TO recipients by pressing the @ mark, and the ability to close the TO field using the Escape key. It also resolves issues from previous ChatWork site updates, enhances the input behavior, and allows Undo for all button edits.
