Need help for a jump system!

How do i make a system where you jump on a custom key on the keyboard? I use GUI so if it is possible to make a system like that please help me

You could try taking a look at these.
Also, the best way to make the jump react to a keypress is to make an ability, then trigger it to jump upon cast. But first make the abilities hotkey the key you want to trigger the jump.

Hope I helped.
