Doc navigating suggestions.

[ApostolosB]

Current implementation causes a few issues.

Arrows should scroll the the document (up down left right) and on the end of a page the down arrow should move to the next one. Same for scrolling with a mouse or trackpad on a laptop.

Space can be used to move to the next page and shift+space to move to the previous.
