I'm using the Microsoft Sculpt Keyboard with my Macbook Retina, on Yosemite. This ergonomic keyboard has a split Spacebar key, like so:
I want to remap the left Spacebar key to Backspace to simplify my typing. On Windows, a custom driver enables this remapping out of the box. However, this driver is not available on OS X.
I've already installed Karabiner and experimented with remapping keys. When I start up the EventViewer in Karabiner, both keys show up as
KeyCode::SPACE. Is there a lower-level keycode I can access to differentiate between the left and right Spacebar keys?
Any alternate solutions are also welcome!
