On a personal note, since I stuck for the next 5-6 weeks with no right arm I've started to fully take in the option of doing everything onehanded.
The keyboard is especially tiring since my arm now travels a whole lot more, and my shoulder especially is taking a beating.
I've also moved my logitech mx 3s on the left side of the keyboard, and switched the left and right mouse buttons, and let me tell you, it's a mental trip. But surprisingly it's easier than without switching. At least for the left click (now the right). The right is still asking me for dedicated concentration.
