Many of you have asked about the layout and keycaps of the UHK, so here they are.
This is the UHK ANSI layout:
And this the UHK ISO layout:
We use OEM profile keycaps, so each row is angled. We use the following angles:
Keycaps of the same width and angle can be exchanged. Please note that there's a standard bump on the F and J keys to make touch typists easily locate these keys without looking – this might not make them suitable for replace.
The rightmost keys of the UHK are shorter than the standard by 0.5U. This is to make the UHK as compact as possible, and increase the symmetry of the keyboard halves.
Given the above, standard keycap sets that are available on the market won't fit the rightmost keys, but almost all keys can be purchased individually from the market with the exception of the R1 1.5U and R4X 1.75U keycaps, which are non-standard.
Our keycaps are made of ABS. We'd like to offer PBT keycaps in the future, but we don't know when we'll be able to provide them.
As for now, we can only provide US printed keycaps, and blank keycaps. No language-specific layouts, or Dvorak, Colemak, etc. printed keycaps are available. The labels of our keycaps are laser-etched.
