DESCRIPTION
A simple script used to check if a given key is valid for for the Set Key command. This is useful when the user would like to use a keyboard key as shortcut/hotkey in their script but need to check if the key is a valid one.
USAGE
load the script using the run command
check_key (keystroke)
If the key specified is a valid one as defined in Set Key then it returns the value of the keystroke. Otherwise, it returns None.
For an example that calls this script, see Jump.
