Ironically enough, talking about cutting expenses, the keyboard in the photo could easily cost 10 times more than the typical 100% keyboard you'd find in a corporate office.
Even though I told you don't ask me why.. you're asking me why. But I'm a good donut so I went back:
They dont have to press BOTH keys to press space, they just didnt have a spacebar key that is the correct size to fit, so they put those 2 random keys on instead until they get a permanent keycap set that all fits.
Split spacebars are thing mostly because of layouts that won’t support a normal spacebar key. But, since most of these keyboards have user created and designed firmware, one could assign those spacebar keys to do anything.
I have a few keyboards with split spacebars where the “right” spacebar is normal; it’s just a spacebar but small. The “left” space does dual duty; tap it and it’s a spacebar, hold it down and it becomes a modifier key for a custom layer. Custom layers are used on small keyboards to make the “missing” keys available, sort of like how a phone keyboard has number layer and symbols layer.
I fully embraced this habit of split spacebars because I cannot train myself to use my left thumb to hit space for the life of me even though I’m a touch typist. Since my right thumb is the only digit hitting space, may as well get some use out of the rest of the space taken up by that spacebar.
it is possible if you get enough time to think of every word, you just need to to find synonims so you don't write specific letters, often needing to switch both words/speech style
(it's very difficult though, I've been writing this comment for 5 to 10 minutes)
Definitely unneeded. The ending letter of the series of letters we employ to form words is especially useless, but to be honest the first is mostly superfluous too
As someone that into mech keyboard hobby, I can say that's still perceivable for average user as you still retain the familiar "qwerty" layout.
Look up stenograph keyboard. They have lesser keys but allows someone to write higher wpm and programmable though I don't think they would fit for average office workload (unless you types a lot).
