deskthority

And this is exactly why I switched to the fn/spacebar thing, frees up modifier keys

Does that interfere with other keys when you type fast?

Thankfully, I don't type too fast ;) Seriously though, I've had no issues. In case I need a proper spacebar (e.g. for games), I've set capslock to switch to a layer that removes fn from spacebar and sets right ctrl block to an arrow cluster ...

I'm a programmer myself, pretty allergic to split spacebars and to wasted desk space. I suggest you give 60% a chance, and turn your spacebar into a fn key (essentially, make it a dual-use key).

I've been using this setup myself for some time now and haven't looked back. A well thought-out function ...
