In my opinion, relying on keystrokes for doing things is not a problem but a future. If you use Sublime Text very often and try to learn tricks you will find yourself touching mouse less and less.

The problem with Vim is that it is not designed for my shiny MacBook Air keyboard, it can't get benefit from all modifier keys other GUI text editors uses.

I don't know much about computer history, but I believe keyboards that Vim is designed for didn't have any modifier key but Escape. I guess they didn't have Shift too. That's why old programming languages are all uppercase.

Anyway, don't love your technology: http://prog21.dadgum.com/128.html
