As a user, I can't easily move to the previous (or next) set of revisions easily without using the mouse.
Currently, if a user wants to move both pointers at the same time they need to click and drag the pointers twice, once to move the first pointer, and a second time to move the second one. While this makes perfect sense when the revisions are far apart, it is quite cumbersome when one wants to move to the previous (or next) two revisions.
From https://www.mediawiki.org/wiki/Topic:Tnzvxtfzp9oqsw5v :
Keyboard shortcuts to move in each direction:
Shortcut to move both pointers ( [Ctrl] + [Alt] + [←] [→] ) - simultaneous move the pointers to the two previous revisions.
Shortcut to move one pointer ( [Ctrl] + [←] [→] ) - move the left or right pointer to previous or next revision
For the second shortcut since there are cases where one would want to use either the left or the right pointer, maybe these would be better:
Move right pointer - [META] + [⇧Shift] + [←] [→]
Move left pointer - [META] + [←] [→]
(Now not from ticket)
But feel free to change the shortcuts, ideally after testing the idea with others!
