Google Chat 改行キー設定 is a free Chrome add-on developed by 【NXTED】M.F. This add-on provides a feature that allows users to customize the behavior of the Enter key when using Google Chat.

With this add-on, users can choose from four different settings for their Enter key behavior:

• Pressing Shift + Enter will create a new line, and pressing Enter will send the message (default setting).
• Pressing Enter will create a new line, and pressing Shift + Enter will send the message.
• Pressing Enter will create a new line, and pressing Ctrl + Enter will send the message.
• Pressing Enter will create a new line, and pressing Alt + Enter will send the message.

To switch between these settings, users can access the add-on's popup menu. It is important to note that after changing the settings, users need to refresh the Google Chat page for the changes to take effect. This feature is also available in the Google Chat app, but users will need to reopen the app after changing the settings.

Please note that this add-on has been tested on Windows 11.
