I've used a US-QWERTY keyboard layout my entire life. I've seen other layouts that do things like reduce the size of the enter/backspace keys, move the pipe operator (|) and can't wrap my head around how I would code on those.
What are your experiences? Are there any layouts that you prefer for coding over US English? Are there any symbols that you have a hard time reaching ($ for example)?
Does Dvorak count? I switched over when I made an egrodox style keyboard which in itself made typing generally more comfortable.
I've been using Dvorak for over 15 years. There are dozens of us!
