TAGGED_USE
Description:
This make a radius trigger script run only while the player
is within the radius and is pressing the USE key.
NOTE: you may need to add the TAGGED_INDEPENDENT property to your script, especially if it has any WAIT commands, otherwise the script stops running as soon as the player lets go of the USE key.
Example:
This radius trigger script will fire off once if we are inside it
and press the USE button.
