Arguments: window buttons key-code
This generic function is called when the user when the user releases a keyboard key. An application may add methods to this generic function to respond to keyboard events in its windows.
window is the window that had the keyboard focus when the event occurred. The keyboard focus is usually indicated by some sort of highlighting.
buttons is an integer indicating which mouse buttons and shift keys were down when the event occurred. The value is the result of applying logior to the values of the following bit-flag variables:
Other bits might be turned on as well, so functions such as logtest should be used to determine whether a particular mouse button or shift key was down; for example,
(logtest right-mouse-button buttons)
will return true if and only if the right mouse button was down. For "down" events, the value includes the button or key being pressed now; for "up" events, the value does not include the button or key being released.
key-code is an integer representing the key that
was released. If an alphanumeric character appears on the key, then
key-code is the char-int of that character. Otherwise, key-code is the
value of one of the character name constants beginning with "vk-". The
value of the constant key-names is a list of all of the
"vk-" character names.
