Some keys in my keyboard came to a sticky end after a catastrophic coke spill. I do not intend to replace the old keyboard, since the whole laptop will be replaced next year.
The keys in question are: arrow up, arrow down, shift and '/'.
Shift has a twin brother on the west coast, who's doing all the work now, and I could rewire '/' as 'delete' (now I realize this was a totally useless key) with the xmodmap -e 'keycode 119=/' command. That is, pressing 'delete' outputs a '/' now.
To discover how to replace the keys I use xev. I intend to replace arrow-up and arrow-down for pgup and pgdn respectively. Unhappily arrow-up/down do not have output. I know that pgup and pgdn are keycodes 112 and keycodes 117. But what should I fill in in the xmodmap -e 'keycode <value>=<action>' pattern asxmodmap -e 'keycode 112=' and xmodmap -e 'keycode 117='
