Jump Key Can Be Disabled?

I'm making a special type of jumping for my character that uses the platform behavior. When the player holds down the X key the character gets into a jumping position and when released the character will jump. Everything is perfect except for the fact that there has to be a key for platform behavior to jump with. If I set it to X then the player will jump without a warmup. Is there a way to disable the jump key?

Set jump strength to 0 and then have something like

X released: 
-> Set Jump Strength to 500 (or whatever you want)
-> Jump
-> Set Jump Strength to 0

Ok I just hope I can fit that in my extremely unorganized list of events. Its pretty much another Platform Behavior+ Custom Platform Behavior thing >.<

Organising events into groups and making comments is a very good habit to have.
