Assign hotkey combinations to functions in your add-on.
Usage
To define a hotkey combination, create a Hotkey
object, passing it the combination and a function to be called when the user presses that combination. For example, this add-on defines two hotkey combinations, to show and hide a panel:
// Define keyboard shortcuts for showing and hiding a custom panel. var { Hotkey } = require("sdk/hotkeys"); var showHotKey = Hotkey({ combo: "accel-shift-o", onPress: function() { showMyPanel(); } }); var hideHotKey = Hotkey({ combo: "accel-alt-shift-o", onPress: function() { hideMyPanel(); } });
Choosing Hotkeys
Hotkeys should be chosen with care. It's very easy to use combinations that clash with hotkeys defined for Firefox or for other add-ons.
The following commonly used hotkey combinations will not pass AMO review:
accel-Z, accel-C, accel-X, accel-V or accel-Q
If you choose to use a key combination that's already defined, choose one which makes sense for the operation it will perform. For example, accel-S
is typically used to save a file, but if you use it for something completely different, then it would be extremely confusing for users.
No matter what you choose, it's likely to annoy some people, and to clash with some other add-on, so consider making the combination you choose user-configurable.
