Splitting a stack of items?

[Michi]

How do you split a stack of items in your inventory?

[Jimmious]

Double click them

I've got used to shift+click them in many games. Could that be added as additional hotkey?

Shift + click moves things to the stash.

Pick up the stack with left click, then right click to split the stack.

Yes, but I could set it new buttons. I've already moved to stash so much items accidentally.
