-Combo options available and their defaults:
- keys : [] - An array of the keys pressed together to activate combo.
- count : 0 - The number of times a counting combo has been pressed. Reset on release.
- is_unordered : false - Unless this is set to true, the keys can be pressed down in any order.
- is_counting : false - Makes this a counting combo (see documentation).
- is_exclusive : false - This combo will replace other exclusive combos when true.
- is_solitary : false - This combo will only fire if ONLY it's keys are pressed down.
- is_sequence : false - Rather than a key combo, this is an ordered key sequence.
- prevent_default : false - Prevent default behavior for all component key keypresses.
- prevent_repeat : false - Prevent the combo from repeating when keydown is held.
- on_keydown : null - A function that is called when the combo is pressed.
- on_keyup : null - A function that is called when the combo is released.
- on_release : null - A function that is called when all keys in the combo are released.
- this : undefined - Defines the scope for your callback functions.
