Suggestions for a broken hand?

i broke my right hand playing basketball tonight. splint on, prognosis is 4-6 weeks in a cast that will likely be high enough on my hand to greatly reduce finger mobility. as it stands now, i can only type w/my left hand and have moved the mouse to my left and switched the right and left buttons, but typing w/ one hand is excruciatingly slow and error-prone. i'm sure practice makes perfect but right now it is frustratingly slooooooooooow.

maybe best to ditch natural keyboard for a 'normal' one as the keys on the natural are so farther apart.

i wonder if there's a key mapping that's ideal for left handed only typing. like dvorak for lefties

any tips on how to get by on a computer with a busted hand?

thanks in advance
