Clientside I am most times using timeouts of 0.05 seconds.

The script should react immediatly and not lag behind a bit.
If you don't want the action to be repeated too often there are two ways.
The first way is to make sure that the key has been released before it has been repressed.
The second way is to count the time that has passed since the last action was triggered by the key.
