Left pinky for ctrl (capslock) and right ring finger for L. Works incredibly well for my hands (a quality keyboard helps too). The capslock mapping is obviously meant for vim but works great for many shortcuts like this (ideally there would be a second ctrl/esc and other modifiers to operate with right pinky comfortably, starting my first custom build soon...).

Now you have Ctrl on home row, instead of two rows down.

On a standard PC keyboard, I just use my palm to hit Ctrl (part of why I detest keyboards where Left Ctrl is not at the bottom left corner.

Some smaller keyboards (including laptops) make the control key small or add an "Fn" key to the bottom-left corner (Apple does this). I tend to hit Ctrl with my left hand, so mapping caps lock to Ctrl makes it more reliable to hit.
