Looking for good keyboard only games.

[Sethlol]

Been having tons of fun with Binding of Isaac lately and I absolutely love that I don't have to use a mouse to play but only a keyboard, mostly because I like to play games on my laptop and don't want to bother having to always carry a mouse with me.

So does anyone know some good games that can be played just by using the keyboard? I don't care if they are new, old or indie, I love 'em all (although I do prefer if they are on Steam).

Before someone mentions this: I do know that most console emulator games can be played with only a keyboard but I've played through most of the the ones I find interesting.

Bumping this since no one answered last time. EDIT: guess I can' do that.
