Object PmaKey (Key)

The object triggers the onKeyDown and onKeyUp events of this object after pressing the key or their combinations.
This object is obsolete (but functional) and it is better to use the PmaRoot.onKeyPress event.

No other Pma objects can be created in this object.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.

It is recommended to enter only the more system key combinations like for example Ctrl+Alt+K or F2 key, etc. But some of the keys can already be disabled by the Windows OS and they will not be functional here.
If other keystrokes have to be caught in general as, for example, Esc, etc., then it can be done in the PmaRoot.onKeyPress event.
