/etc/inputrc "connects" PgUp and PgDwn to "beginning-of-history" and
"end-of-history". It would be much more useful if these were
"history-search-backward" and "history-search-forward". Maybe "beginning-"
and "end-of-history" could be reached with modifiers.
Another point is that users' .inputrc files are ignored. It is trivial to
do something like this:
--- 8< --- /etc/profile ---
if [ -f ~/.inputrc]; then
--- 8< ---
The sourcing of user's .inputrc is fixed in the setup/etcskel
in Raw Hide.
... and as for the rest, I'm a little leery of changing
the default keybindings too much in a point release.
