in my vimrc, which gains me all the ease-of-typing I really want. I don't think it'd really be worth anything as drastic as actually creating a new keyboard layout.
Then again, I don't use lisp all that often, so YMMV on that point.
I have (, [, and { on regular keys on my keyboard. Shifting the key yields the other pair: ), ], }. But since Emacs autocloses parens I rarely need to do this.
What keys did you swap if you don't mind me asking? I've been planning on doing this, but just haven't figured out the optimal location, especially for a laptop.
[] being easier to type than () is a decent point, though. I wonder if it'd be worth remapping your keyboard to swap them if you write a lot of lisp.
