Can I disable alt-left and alt-right actions ?
I use a lot of different keyboards and OSs in my job and as a result I am often prone to hitting odd key combinations. The worst of them all is that when editing in forms on web browsers I am always, always, always accidentally hitting alt-left arrow instead of shif-left arrow. When I do this I get taken back a page by my browser and lose whatever email/forum reply/order I have been entering. I also scram loudly everytime. It's starting to scare my neighbours. Is there anyway at all to turn this off in firefox, or if not, is there a browser that does not use this key combination as a 'back to last page' shortcut?
