I am a programmer and sometimes I get Repetitive Stress from using the keyboard and mouse a lot.
I find that my hand gets 'crampy' after a while and I have to keep switching hands for the mouse.
Is there anything else I can do to minimize this?
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
I strongly suggest the Kinesis Freestyle. Texter 0.6, autohotkey, etc do help.
Take time off from keyboarding. A week is doable, yeah?
