This was ... about 20 years ago, and I don't even remember why I wanted to do this, but I found some software that let me remap the keyboard somehow - so I picked a key (probably caps lock?) that would "mirror" the standard QWERTY layout.

F would become J; S would become L, etc.

I was able to have a fairly decent input speed.

I wish I remembered why I did this. I think I had some tedious task that I couldn't figure out how to automate, that required me to have one hand on the mouse[1] most of the time, and swapping between keyboard and mouse all the time got tedious enough that I invested the time.

[1] Yes, the mouse. :)

edit: Ah, someone already made the same suggestion elsewhere here! I'm glad it's a popular choice.
