Define an activation key for a button

1.0.0 As a string this option will set the key to be listened for. It should be a single character (since multiple characters can't be pressed at the same time!). The character is case insensitive. The object form of this option provides additional control over which key(s) will activate a particular button, providing the option to define filtering by meta keys such as shift, alt and ctrl. The object properties available are: * `key` - The character to listen for. The character is case insensitive. * `shiftKey` - When set to `true` activation will only occur if the _shift_ key is also being held. * `altKey` - When set to `true` activation will only occur if the _alt_ key is also being held. * `ctrlKey` - When set to `true` activation will only occur if the _ctrl_ key is also being held. * `metaKey` - When set to `true` activation will only occur if the cmd key (Mac) or Windows key (Windows) is also being held. Multiple options can be defined if you wish to restrict activation to a specific, complex, key combination. Buttons has the built in ability to activate buttons through keyboard key presses and key combinations. This is to aid accessibility and provide complete keyboard navigation of your table. For example, with using Editor, records can be added, edited and deleted without touching the mouse! Key presses are only processed when the document has no element that is actively focused. This means that typing into an `-tag input` element will not accidentally trigger a button's action! Please note that for Adobe Flash based buttons, key activation simply will not work! This is a security feature implemented by Adobe - such buttons _must_ be clicked on to activate them.
