Ugh.
Matias Mini keyboards have *three* keys from the sixkey.
AltGr is necessary to type in plenty of national layouts. Right Control is useful to alternate hands without cramping the left pinkie.
So I got a detail on a keyboard I don't own wrong. Still doesn't invalidate my point that it doesn't fit the demographic 75% keyboards are meant to fill. You're missing the forest for the trees if that's all you got out of my post.
I agree about right Alt and never said it wasn't important. There aren't many 75% ISO boards, this could be part of why.
and apart from being wrong, be so kind and don't put ridiculous BS into my mouth. Most of these layouts are relatively well defined.
~40%
alphanumeric section - number row
60%
alphanumeric section
~65%
alphanumeric section + arrows and something
70%
alphanumeric section + function keys
75%
alphanumeric section + function keys + arrows and something (without the Model M spacing in navigation section)
I fail to see how I was putting "ridiculous BS into [your] mouth". I was just trying to draw a comparison that I hoped would show you why I don't consider it a 75% board, I never said you were confusing 40% and 60%. Even Matias himself sees that it doesn't fit everyone's use case which is why he put together his own "60%" (his classification choice, not mine) with a different set of keys from that nav cluster.
The only layout I said wasn't well defined was 75%, and that one is true, almost all 75% on the market have slightly different layouts. What they have in common is that they have as many of a TKL's keys as they can fit into as small a space as possible. The Matias doesn't fit this description.
Whatever the case, I give up. You clearly expect something different out of a 75% than I do. Let's just agree to disagree.
I guess this does add to OP's answer though. You cant have many people owning a style of board if you can't agree what that style actually is.
