* Remove ctrl-up/down in insert
* Reorganize insert keys and docs
* Improve page up experience on last tutor
The last tutor page can page down multiple times and it will break the
heading on the 80x24 screen paging when reaching the last page, this
keeps the style the same and make sure page up and down won't break it.

The tutor file is loaded as .txt which can potentially spawn a
language server. Then the path is unset, but the LS remains active.
This can cause panics since updates are now submitted for a doc
with no path.
As a quick workaround we remove the extension which should avoid
detection.
Fixes#3730
