Minecraft changing controls?

When using mods in Minecraft, some controls start with a default "NONE" as their control button.

Is there any way I can change existing controls to "NONE" as I have so many mods I do not have enough buttons for them all, and they are very annoying as I keep pressing the wrong buttons by accident.

I think that if you change one of the controls for the mods to the jump button (just an example) and then change back the button to jumping it will work. Not sure but worth a try

You can just put them all on the same button ( like page down for example)
