Shortcut key for drop/insert 10 items

[JasonC]

TL;DR

A shortcut key for dropping / inserting 10 items at a time.

What ?

The Z key (by default) currently drops / inserts 1 item at a time. I'd like an additional shortcut for doing this with 10 items at a time.

I don't know (or really have much of a preference for) what the default key assignment for it should be. Perhaps it could be shift+Z, or just unassigned by default.

Why ?

This could be helpful in a number of places but especially early in the game when manually inserting fuel into burners and furnaces, ammo into turrets, items into chests, etc.
