key-was-down-p

Function

Package: common-graphics

Arguments: virtual-key-code

Returns two values indicating whether a particular key on the keyboard was pressed at the time the event currently being handled occurred. The argument should be either the char-int of some graphic character or the value of one of the symbols beginning with vk-. This check is done asynchronously.

The first value indicates whether the key was down when the current event occurred. The second returned value indicates whether the key is toggled. A key is toggled if it has been pressed an odd number of times. For keys such as CAPS LOCK and NUM LOCK, this indicates whether the key is on.
