I've just reviewed the behavior of apps on macOS (like Messages, Bear, Notes, Reminders, Mail) and each app has different behavior for CMD-Backspace, ie.:

• Messages: delete chat (same as BeagleIM)
• Bear: delete note
• Notes: delete line
• Reminder: delete line
• Mail: delete a message in the list view and delete a line in the message entering window

As you can see, CMD-Backspace means delete line or item (ie. note, chat), so usage of CMD-Backspace is correct in this case.

On the suggestion of usage CMD-W to close the chat - it is not how applications behave on macOS. CMD-W means "close the window" not close the chat!

I'm open on other alternatives for a shortcut to close a chat, but for now, closing on CMD-Backspace when the input field is empty looks like a most viable solution.

CMD-W is widely used to close tabs, see any browser (safari, chrome, brave), or terminal emulators (iterm2 and terminal.app both). Text editors also do behave like this. VSCode to name one.

CMD-Backspace in Apple Messages behaves exactly as I described it: When a text-entry field is focused, CMD-Backspace deletes the whole lin. It does not close the current chat. Also you've mentioned a few apps that behave like this, i.e. when inside a text entry widget, CMD-Backspace removes a line. IMO that underlines that beagle-im should also remove a line, instead of closing the chat.

More examples are Telegram and WhatsApp.

I've double-checked and Apple Messages closes chat (and even deletes the content of the chat) when text field has focus but it is empty and you pressed CMD-Backspace.

Due to that, I'm going to follow what Apple Messages does: if there is a line - remove it, if text filed is empty - close chat.

Nice, thank you!

It works great thanks for solving this!
