One little thing I noticed about "space".
Let's say you want to create a point at x=5 y=7 z=2
Normally you would type "tab" 5 "space" 7 "space" 2 "space" "enter"
But since you altered space key which works as enter you can't use space there.
Luckily Michael thought this possibility and you can use "comma" key instead of space there.
With your workflow, it's gonna be like this: 5 "comma" 7 "comma" 2 "comma" "space"
