Regular layout unsplit qwerty kb!

I believe that would count as an ergo split columnar keyboard?

I thought it was asking for a specific keyboard, not a type of keyboard, haha, misread it, changing my vote

[zinc sedge]

that would be the top option, a staggered kb. Staggered because the keys in one row don't line up horizontally with the keys above and below that row.

Oh ok, TIL. When I googled "staggered keyboard" every single image was something crazy and non standard so I assumed it was something else lol

@austere cedar and @velvet flame just curious what keyboard models (or keyboard alternatives) you came from, based on your votes here. Thanks.

My daily keyboard is a Velotype PRO, I type in syllables

that really is something wilder, thanks for letting me know
