Slightly off topic. But when I got my first 60% keyboard I started using the SpaceFN layout (via TouchCursor on Windows) and never looked back. Even on larger keyboards.

SpaceFN turns your space bar into a meta key, and arrows/home/end/pgup/pgdown are all reachable from the home row. I can't go back.

You can't use it in application that need to know if your holding down the spacebar (graphic design software, games). I switch it off for those. But otherwise I haven't had any issues (besides TouchCursor, which is buggy and need a restart every now and then).
