"accel-s"
"meta-shift-i"
"control-alt-d"

Modifier keynames:

  • shift: The Shift key.
  • alt: The Alt key. On the Macintosh, this is the Option key. On Macintosh this can only be used in conjunction with another modifier, since Alt-Letter combinations are reserved for entering special characters in text.
  • meta: The Meta key. On the Macintosh, this is the Command key.
  • control: The Control key.
  • accel: The key used for keyboard shortcuts on the user's platform, which is Control on Windows and Linux, and Command on Mac. Usually, this would be the value you would use.
onPress : Function

Function that is invoked when the key combination hotkey is pressed.

Methods
destroy()

Stops this instance of Hotkey from reacting on the key combinations. Once destroyed it can no longer be used.
