On my [hp Spectre x360]({% post_url 2016-07-26-hp-spectre-x360 %}), the <kbd>Ins</kbd> key is only
reachable via the <kbd>Fn</kbd> key as in <kbd>Fn</kbd>+<kbd>PrtScr</kbd>.
So I wanted to swap both keys. System-wide - so not only in X (using `xev`).
I finally found [this](http://superuser.com/questions/290115/how-to-change-console-keymap-in-linux)
which suggested the following procedure:
1. Dump the current keyboard layout:
sudo dumpkeys > backup.kmap
1. Check the keycodes you want to change (<kbd>Ins</kbd> = 110, <kbd>PrtScr</kbd> = 99):
sudo showkey
(When you're done, wait 10 seconds for it to exit automatically.)
1. Copy the dumped keyboard layout:
cp backup.kmap ins-prt-swap.kmap
1. Edit it to swap all occurrences of `99` to `110` and vice versa, e.g. change:
keycode 99 = ...
...
keycode 110 = Insert.....
to
keycode 110 = ...
...
keycode 99 = Insert.....
1. The suggested `sudo setcon --save` didn't work for me, but Ubuntu loads the active keymap from
the file `/etc/console-setup/cached.kmap.gz`. So I gzipped my `ins-prt-swap.kmap` and copied the
resulting `ins-prt-swap.kmap.gz` to `/etc/console-setup/cached.kmap.gz`.
