    app: fix #5153 keyboard shortcuts Shift+[ and ] don't work on most keyboards
    
    On most keyboards the [ and ] keys are shared with { and }. Which means
    that if you press Shift+[ you get {. We were using this key combination
    to increase the tool's size by 10 and the other to decrease it by 10.
    
    However, on all keyboards where these keys share the same physical spot
    on the keyboard, this wasn't working.
    So, let's change the actual keys to do this to { and }.
