Hi Guys, just thought I'd share my layouts and build photos.
I'm a leftie and have been using an Ergodex for years (the ergo keyboard with removable sticky keys), and I even wrote Windows 7 drivers for them too. Anyway, to complement it I bought one of these Ergodox keyboards and have been tinkering with it off and on since i built it a few weeks ago. Gotta say I'm loving it.
Keys wise I ordered light blue, black and dark grey keys from
www.wasdkeyboards.com, yes expensive but i've not seen any other places that do keycap singles from. I went with a number set, a qwerty set, a cursor key set and a few tab 1.50 keys. For the 2.00 keys I used numpad Enter keys and for the thumb keys above them row 1 keys. This means that when pressing them you don't press the ones underneath. Oh I also used row 2 blank 'home' keys on the PgUp/Home keys so again you can locate the keys without looking. That works well.
Since I do programming and various command line activities the default ergodox layout wasn't good for me. I also wanted an inverse T cursor key layout. Having the cursor keys under the right hand 'home' keys makes it a breeze to move around after typing in the editor i use. Also having the backslash and forward slash keys near where they are on a qwerty keyboard helps too.
Thanks to another poster on here I too added a gaming layout with a sort of weird inverse mirror one hand qwerty layout. The idea being that i just use normal game keyboard layouts/configuration but use my right hand on the keyboard and left hand for the mouse which is the opposite for normal gamers. My Ergodex layout is pretty much identical except for an extra row of numbers above the normal number keys.
I've also ordered, but they have not yet arrived, some textured Enter keys and some textured tab keys. I plan to use the textured keys for the space and backspace keys since those are the ones you use most on each thumb. I will use the textured tab keys as layer shift keys since the texture I ordered was called 'dot grid' and that kinda looks like keys
Lastly I am using Cherry MX clears for all keys except the modifier keys which are Cherry MX blues. It's really nice to have different feedback for keys with special meanings.
Enjoy!
