Описание тега keyevent

A KeyEvent is an event that is triggered when a key is pressed, released or remains pressed on a keyboard input device. The event can contain:

• info about particular key that was pressed/released
• how long the key was pressed
• whether any modifier keys were also pressed (such as Ctrl or Alt).
• type of event - press, release, other (for example character was typed, regardless whether key was pressed or released)

Some platforms/keyboards may generate auto-repeat key events - same character is typed repeatedly while key remain pressed
