Keep arrow and special keys in insert (#3915)

Browse Source 
* Keep arrow and special keys in insert

Advanced users won't need it and is useful for beginners.
Revert part of #3671.

* Change text for insert mode section

Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>

* 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.
