Keyboard activation on a hovered button?

[pnill]

Is there a way to make it so a keyboard key activates a button that's hovered over by a mouse? I was thinking I could just Use the IsItemHovered() code then check for a key press there, but was wondering if there's an alternative way I should be doing this that's already supported and doesn't require navigation with the keyboard ahead of time.

EDIT:
So using IsItemHovered() and IsKeyPressed() just after creating the button does seem to work, but not sure if it's efficient to constantly pole for that, though I believe this happens in the background anyways to change the style of the button, just seems redundant to be doing it again... I guess one option would be to re-create the ImageButton routine and implement it with the input I'm looking for since I don't care about the mouse click on it just if the mouse is within it's rect and a specific key is pressed.

This is how immediate mode UIs work - we keep doing things over and over again. 99% of time cost is negligible. If you are concerned with performance - profile first, optimize later.
