In the Keypress section, it would be great to have a dropdown menu, similar to what the Stream Deck software offers for E-Keys and other keys.

This would help in cases where the user’s keyboard doesn’t have certain keys by default. For example, someone might want to use a key from the numeric keypad, but they’re using a 60% keyboard that doesn’t include a numpad.

A dropdown would give users more flexibility when selecting replacement keys.

It seems like a simple improvement: instead of only having the "capture pressed key" field, add a dropdown list with all possible keys.

F13 = Shift+F1

F14 = Shift+F2

I assume setting these as macro keys would get you where you needed without code changes.
