Idea for new Focus Mode: dpad_and_keyboard

[danideter]

Hi there,

I'm making an app primarily for mobile that I might like to port to PC someday. For a quiz minigame, if the user is using touch or a mouse, it makes little sense to grab the focus of the last selected button. However, if the user is useing a keyboard or a dpad, focus helps the player know which button they are about to press:

Currently, the focus modes are:
None
Click
All

Where all includes click, dpad, and keyboard. Would it be useful to others to provide a 4th option: dpad_and_keyboard?

I was hoping it would be a relatively simple change, and tried to make a PR. Unfortunately, I couldn't find where the logic for the click modes are implmented. I did find the following files which would likely need to be updated:

I think we need to handle this differently. We should make it so mouse-produced focus doesn't have a visible outline by default, as I proposed in #6577.

This way, you still preserve expected accessibility behavior (clicking with the mouse defines focus), but it doesn't visually get in the way.

Ah yes, that would work too :)
