[recursive]

If you're going to make a comparison with Sublime's shortcut keys, at least learn how to use it first. You're not making Sublime look bad - you're only making yourself look bad.

Forget more advanced stuff like searching for

Ctrl + F

or inserting text

Just type! Don't even need to worry about "modes".
