Chatworkをいじる拡張 is a Chrome extension developed by myo.ryo. This free extension falls under the category of Browsers, specifically Add-ons & Tools.

The purpose of this extension is to make Chatwork more user-friendly. With this extension, you can easily insert [info] tags by selecting text in the input field and pressing ctrl+i. Additionally, you can insert [title] tags by pressing ctrl+space. Mac users can achieve the same functionality using the command key.

Another useful feature of this extension is the ability to remove emoticons from selected chats. Simply select a chat containing emoticons and click on "顔文字削除" (Remove Emoticons) to make them disappear. It's worth noting that this removal is temporary and does not permanently delete the emoticons.
