Why Mousetrap?

There are a number of other similar libraries out there so what makes this one different?

• There are no external dependencies, no framework is required
• You are not limited to keydown events (You can specify keypress, keydown, or keyup or let Mousetrap choose for you).
• You can bind key events directly to special keys such as ? or * without having to specify shift+/ or shift+8 which are not consistent across all keyboards
• It works with international keyboard layouts
• You can bind Gmail like key sequences in addition to regular keys and key combinations
• You can programatically trigger key events with the trigger() method
• It works with the numeric keypad on your keyboard
• The code is well documented/commented
