I have caps remapped to esc when tapped, and ctrl when held. Takes perhaps a weekend to get used to, but once the muscle memory is there it feels incredibly comfortable and natural.
Is this macro mapped in vim or OS level? Sounds interesting.
I have hesitated many times to set this up but I don't want to get used to something that I cannot set up in less than 30 seconds on a new machine.
Not having Escape where CapsLock sits on a new machine already makes it infuriatingly unusable already :)
Which tool can do that kind of wizardry? I've seen either but not both.
