An update, I modified the code so that XK_Left/Right/Up/Down are also recognised. Note that the erkeybd-library is changed, so you need to run the 'Install KeyBoard Hack' again (1)Cancel Uninstall, 2)OK for Install, 3)leads to reset of device). The install also copies the bitmaps, so if you do not like them change them and run the install again.
Source code will be updated in the
dr1000-hackx BitBucket archive.
