Fixed: Fix SHIFT+PAGE_UP and SHIFT+PAGE_DOWN behaviour to scroll 1 line of scrollback history instead of scrolling command history or changing pages

Browse Source 
This will work for both `SHIFT` extra key and hardware keyboards. The `SHIFT` extra key can be long held to lock it in an enabled state and `PGUP` and `PGDN` keys can be long held to repeat scrolling.

Closes #867
