Yes, you can bind something to the other spacebar. Shift, a FN key, backspace, enter, a letter, whatever you want. Normally you would have 8 fingers on the alpha cluster (the letters) and use a thumb for space thus using 9 digits (before someone comes after me for calling thumbs fingers lol). By splitting the space you effectively gain the ability to type with all your digits by giving each thumb a separate key. You can also split the space in more than two keys. Personally I quite like two keys per thumb.
This picture is very concerning due to the lack of letters and punctuation on some of these keyboards. One has "QAZ" in the wrong place, two more lack those letters entirely, and one has gone so far as to remove "L" too. What psychopath designed these?
For letters and punctuation though? Seriously? Like, okay, lesser used punctuation like carets, tildes, lesser/greater than, stuff like that seems reasonable to stick behind a layer. Letters though?
chording (using multiple hotkeys to redefine the char set) requires retraining and mental overhead and can lead to errors. no thanks. I don't even like the superset buttons on laptops, fuck fn keys etc.
That psychopath would be me (for the pink one and the black one, the green one is a vault 35). If you want to have your eyes opened, the black one with the QAZ on the right has an interest check going on now.
I understand removing numpads for people who don't enter a lot of numbers since you have a second set, but removing things beyond that, I don't know, I don't get it. I don't even think I can give up my function row (f1-f12)
As someone who uses a 40s keyboard (no numbers row, kinda similar to the bottom middle keyboard in OP's pic): my wrist pain that I got from typing 4-6 hours a day was gone once I started using them, because they're compact and I don't have to move my hands/wrists at all. When I type with a full-sized keyboard, I have to move my wrist when I want to type numbers, for example. Now I can type for 8+ hours a day without worrying about pain.
Of course, keyboards are all personal preference! That's why I love the mech keyboard community, seeing all the different layouts and shapes people tailor to use for themselves.
It's got lubed KTT Strawberries in it right now. I was going to go with North Poles but I could not get them to fit so I put those in the Mod 005. The caps on the KBt are Drop Dasher which I fell in love with after watching Severance.
