When I posted the original Installing stock Debian on the Samsung ARM Chromebook post, there was a section at the end titled What doesn’t work. I’ve got two of those things working:
Here is the mapping which maps page up and page down to search key + up / down arrow:
! pressing keycode N does action M
! Mods: nothing, shift, Mode_Switch, Mode_Switch + Shift
keycode 111 = Up NoSymbol Prior
keycode 116 = Down NoSymbol Next
keysym Super_L = Mode_switch
I’ve pushed this to Github as 10-xmodmaprc: https://github.com/jmpesp/debian-on-arm-chromebook. On the Chromebook, this file is saved as .xmodmaprc in the root of the home directory. Then, in .xinitrc, I added:
xmodmap .xmodmaprc
This will apply those remappings every time I start X.
I didn’t directly reference that copy and paste didn’t work in the original post except by mentioning that I was trying to remap insert - shift insert is impossible without the insert key :).
However, the Chromebook supports the three finger tap and this will emulate a middle click, which pastes.
