Keyboard numpad

Keyboard (Num0), or autosplitter if it's a PC game. Don't want to buy a foot pedal, and I can't exactly bind a key to my controller if it's a console game. Nor do I have keys left over.

i use space for splitting and backspace to restart but if its a pc game where you have to use space somewhere i either bind it to my mouse extra button or "§" (finnish layout)
