/**
* An AWTKeyStroke represents a key action on the
* keyboard, or equivalent input device. AWTKeyStrokes
* can correspond to only a press or release of a
* particular key, just as KEY_PRESSED and
* KEY_RELEASED KeyEvents do;
* alternately, they can correspond to typing a specific Java character, just
* as KEY_TYPED KeyEvents do.
* In all cases, AWTKeyStrokes can specify modifiers
* (alt, shift, control, meta, or a combination thereof) which must be present
* during the action for an exact match.
*
* AWTKeyStrokes are immutable, and are intended
* to be unique. Client code should never create an
* AWTKeyStroke on its own, but should instead use
* a variant of getAWTKeyStroke. Client use of these factory
* methods allows the AWTKeyStroke implementation
* to cache and share instances efficiently.
