proposal: add page end and page start as key bindings under actions

[jojoknob]

Allow the user to page end to the end of the inventory, and similarly return to the front.
Not sure how this would interact with other areas where page up and down are used.
Repeatedly accessing the end of my inventory (I'm still on main branch) is a chore currently as my inventory is huge.

Perhaps Home and End would be more appropriate keybinds for these
