look at the title, maybe?
i was playing with codes and playing games on the Xbox and saw that some certain buttons only worked after you release the button, so i was thinking about how i could do that in a FPS on scratch, and came up with the [Repeat until <Not (Key) pressed> ] code You can use the code to stop people from abusing a command that has a head of (When [Key] Pressed) and nothing to stop from doing otherwise. Either you can put [Repeat Until <Not (Key) Pressed> ] to make it do something and then put the desired actions after ORRRR the [Wait until <Not (Key) Pressed> ] to make it do nothing until you let go of the button :D
