F4 and F11 cannot be binded

[lip8up]

This cannot work:

hs.hotkey.bind({}, 'f11', function() ... end)

But this can:

hs.hotkey.bind({}, 'f12', function() ... end)

And this also can:

hs.hotkey.bind({'cmd'}, 'f11', function() ... end)

Thanks!

hs.hotkey.bind cannot override system defined shortcuts. Check System Preferences->Keyboard->Shortcuts to see if you have F11 assigned to something, e.g.

I've noticed that it can be inconsistent about reporting an error about this, but even when no error is returned, it won't prevent the system version from being triggered instead of ours.

Thank you very much! My problem has been solved.

I found when I just set the shortcut of the Mission Control as F4, but I don't check the check box to enable it, it also takes up the F4, then, cause the hs.Hotkey.bind for F4 cannot work!

When I enable it, change it to another key, re-disable it, reload the Hammerspoon, and hs.Hotkey.bind for F4 can work
