Alternate keymap for Alpha 28-key keyboard.

Assuming you've followed all the instructions from the original post, put my "keymap.c" file in "$qmk-firmware-folder$/keyboards/alpha/keymaps/vderm/" and then run your make command ("make alpha:vderm" while in $qmk-firmware-folder$ where this folder is what you've downloaded from the official github page) to compile the hex file to upload to your microcontroller. I've also uploaded my hex file.

Instead of going up and down layers like in the original Alpha keyboard, I've made the bottom row keys all have alternate functions:

• Like in the original Alpha28 keymap, the 2U spacebar is a shift key when held down and space when tapped
• Z and M are Ctrl keys when held down or Z and M when tapped
• X and N are Alt keys
• C activates the function keys layer (arrows, page up/dn, esc, tab, etc.)
• V activates the characters and numbers layer
• C and V combined activated the F-keys layer (F1, F2, F3, etc.)
• The enter key is an enter key in the home layer, backspace in the function keys and characters/numbers layer and a delete in the F-keys layer
• While in the other layers, the bottom row acts like a "regular" bottom modified row: ctrl, alt, winkey

Here is my keyboard.

• Switches: Aliaz Silent Switches (Tactile), PCB mount, 80g from KBDfans
• PCB board: ordered from JLCPCB, in white
• Keycaps: ebay, can't find link :S
• Bottom plate: I cut a piece of canary wood that was laying around, needs to be varnished; I also need to actually screw the pcb to the wood instead of relying on double-sided tape

Good luck on your build! //vderm
