Sorry if I missed something, but is there anyway at all to change the controls? I want to put fire as something else...

There's no way to change key functions in-game,
but check out autohotkey: http://www.autohotkey.com/

You have to write the script yourself, but it's pretty simple if you read the documentation. You can also get it to apply the remappings in worms only.
I use it to remap capslock to scroll lock as my keyboard has no scroll lock.

Wow cheers man, I'll have to have a look at that. I want to because my spacebar is broken so I need a temporary fix until I get a new laptop...

What does Capslock do??

I thought there might be a WK module for it or something...

Something for the maintainers to consider for a future beta??

Seems like it's already planned. (http://feedback.worms2d.info/forums/5998-worms-armageddon/suggestions/100839-option-to-change-gamecontrols-in-game?ref=title) ;)

Maybe they'll consider adding it sooner if you add your vote :p
