Support numpad Enter key as equivalent to main Enter key

[Zxxxxxl]

Hi, thanks for building this great screenshot tool. I use it often and really like the workflow.

I noticed that the app supports using the main Enter key to confirm or perform actions, but the Enter key on the numeric keypad does not trigger the same behavior.

It would be very helpful if the numpad Enter key could work the same way as the main keyboard Enter key, especially for users who often use an external keyboard or full-size keyboard.

Expected behavior:

• Main Enter key confirms the action
• Numpad Enter key also confirms the same action

Current behavior:

• Main Enter works
• Numpad Enter does not work

Thanks!
