No, He can't. You too can't.

Shortcutd (and another similar package, with less functionality, also using half-pressed camera button - but I don't remember it's name now) allow to use half-press (short and long) for some action. vi_ is proposing, to also use full_press to do some thing.

ho ever, I'm worried a little, about functionality of it - every time you do full-press, You also perform half-press, a 0,1 second earlier This may limit usage of full-press shortcut...
