Input while step over in VS

[LunaMoo]

You could try with gamepad, never really tried with VS debugger, but I do it often when stepping over in ppsspp disassembly while making cheats.
Also when you pause the game using esc on windows at least, whatever keys you pressed will stay pressed after you unpause the game until you press them again ~ which you can use along autofire key to spam any key you need pressed.
