Using AutoHotKey for PC (for MALTRON remap & all special keys)
and KeyRemap4Macbook/PCKeyboardHack for Mac (to use the international 1-6 keys)
and Ukelele for Mac (to remap to a MALTRON keyboard layout)
until the vaporware remapping software actually exists.
I am a huge supporter of the Maltron Layout.
The X key and /? are reversed due to the moved apostrophe key (from QWERTY)
Shift & Control swapped back to match my Kinesis (and almost every other keyboard)
Slash keys on the bottom corners
Dedicated Underscore & Asterix keys on top left
parentheses moved to 5 & 6 keys
=+ key flipped to +=
Currently I'm using the Deck109 on a Mac. My PC relies on having num lock ON, and because this swaps in the 10keypad, it's currently a deal-breaker. Wish I could turn this dependence on the system numlock state OFF!
