anker keyboard escape key
Err, that's an iOS keyboard... (and the key is a Home button)
I would say that your easiest bet would be use use PCKeyboardHack (or KeyRemap4MacBook) to use the caps key was escape. I use this on my mac, as caps is normally useless anyway.
How to Change
- Note that Escape's code is 53
- Locate "Change Caps Lock", double click the key-code there, and to edit to 53
The fn+home key combination works as Esc.
iOSKeyboardEscapeKeyEnabler will enable the home button on the keyboard to function as an escape key.
For some reason Karibiner is unable to read the key, possibly due to it being part of the "Consumer" page and not the "Generic Desktop" page.
