// This is because the mutation always happens after the keypress for
// input (this is especially important for chrome,
// which interleaves deferred commands between keydown and keypress).
//
// For everything else, keypress is redundant with keydown, and also, the resulting default
// dom mutation (if any) often happens after the keydown but before the keypress in webkit.
// Also, if the 'Command' key is held for chrome/safari etc, we want to get the keydown
// event, NOT the keypress event, for everything because of things like ctrl+c etc.

// get a keypress at all
