## key-was-down-p

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.

For a letter key, the key code is the char-int of the uppercase character shown on the key (and NOT the corresponding lowercase character). For a numeral key, it is the char-int of the numeral character. For any other key, the key code is the value of the `vk-` constant for that key (see `key-names` for a list of `vk-` constants); for keys that show both a shifted character and an unshifted character, this constant will be named after the unshifted character.

### GTK Note

The second value (which indicates whether the key has been pressed since the previous call) is not returned on GTK.
