+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.
