Every keyboard I've ever used I've remapped the caps lock to control, whether in hardware (like on my pok3r) or in software (on my work computer). I have a hard time ever using a keyboard without this remapping done.
One row up or down is fine. But home row far left is hell. Maybe it's simply because my hand grew into it over several decades. Instead, I use CapsLock to lock my screen.
Now my capslock is Ctrl. I find that combo to be particularly effective for me.

I use this mapping in my current setup and find it really useful.
