Recently, We have got Drill Through Feature in September 2017 Update in that there is option called "back button" for moving previous dashboard and in similar passion, If Forward Button feature is in...
I don't know why the Forward and back arrows are provided when they don't have a 'next' and 'previous' bookmark that can be assigned to them (I noticed after my original comment that the 'back' arrow is to previous location, which is not necessarily one worksheet forward or back).
