I have my ergodox ez setup like this.

asdf and jkl; all have dual functions when held

a/j = ctrl

; = alt

a turns ijkl into arrow keys (like wsad, but I have a left handed mouse)

k + j = copy, k + l = paste

and so on for symbols, brackets, etc.

The goal is to move from the home row as little as possible. I attempted to gather statistics on most used keys when programming at work, which was mildly successful.

Here's my layout, optimized for left handed mouse use: https://configure.zsa.io/ergodox-ez/layouts/JwoW9/latest/0

That is great! I think there is a lot of room for innovation with dual use keys like this.
