Support for Alternative Layouts
This is a summary of how alternative layouts have been supported by kits such as Colevrak and Homing. It is not a discussion of alt layout performance and development, but if that interests you I highly recommend starting with Pascal Getreuer’s A guide to alt keyboard layouts (why, how, which one?). It’s a concise and comprehensive overview with links to some great sites that go deeper. He also has a separate Links about keyboards page. The Keyboard layouts doc he recommends explains layout goals and metrics in detail, summarizing the alt layouts discussed here as well as more than one hundred others. Sculpted-profile The majority of custom keycap sets are sculpted-profile (Cherry, SA, MT3, KAT, etc. - more on profiles generally here) so let’s start there. Because each row has a unique keycap shape, alt layouts require a unique keycap for each legend that moves off its QWERTY row. At first there were two The Dvorak layout was patented in 1936 by August Dvorak & William L....

Topre keyswitches are mechanical keyswitches that nevertheless incorporate a rubber dome, so they are softer in feeling. They are hard to find on keyboards. Topre is a Japanese company, Tokyo Press, whose main gig is sheet metal pressing for automobiles They have other businesses (including bath tub covers, one of which I own) none of which relates to keyboards. I have no clue how the key switch business started inside such a company.
Hacking Hacking Keyboards was established to make a keyboard designed by a legenday computer science professor at Tokyo University. It has the control key to the left of the A, which makes it easy for geeks to use commands in terminal mode, for instance emacs and vi. The original version had no arrow keys, since geeks use control key combinations to move the cursor, but my version had small arrow keys crammed in. HHK's maker is now owned by Fujitsu.
60 percent keyboards are the size of the Apple wireless keyboard, Standard keyboards have 19 mm key pitch, i.e. the keys center to center (or left edge to left edge) are 19 mm apart. You don't want to make that smaller, so to make a smaller keyboard you just remove keys. A 60 percent keyboard is missing a dedicated function key row at the top, as well as the navigation pad and num pad.
A 40 percent keyboard also is missing a dedicated number row, and has fewer keys left to right also. It's 4 rows tall by 13 keys wide. To enter numbers you need to put the keyboard into another mode or use a function key (function-tab will produce a 1, function-A a 2). Additionally, some of the punctuation requires use of a function key. 40 percent keyboards are four keys high times 13 keys wide. They remain mostly hobby projects that people build from parts, but mine is a commercial keyboard from a company in Taiwan, the Vortex Core. It has no tray extending outside the keys. So it's even smaller than most 40 percenters. It looks normal to me, but other people just laugh.
