Triggered by a silly reason - keeping a keyboard in my locker at work - I've started wondering if I can find a keyboard with the full ISO layout under 41cm wide. Essentially I want to make it easier to plonk in the locker on a tray with my laptop. Right now I have to separately manoeuvre it in. I'm wondering if I should look into an alternative layout. I use literally every key on the board (ok SysRq is rare but I do). Numpad, arrows and navigation all get used a lot. Is there something that isn't lacking too many keys that might work for me? I'm a bit wary of adjusting to new layouts as I also use full ISO keyboards at home, laptop keyboard, etc.
