Saving unit selection on numbers

[nerovesper]

When saving units on selection usually the controller will press shift + <number>
example shift + 1 will automatically select the saved unit.

My question: Is it possible to do this in triggers/Jass?

Well... I got idea that Shift is pressed in Events and numbers are in IF/THEN/ELSE thing.

Like Event - Player presses Shift
If he presses 1 then blah blah and so on.

Dunno if such function exists...

About JASS it could be same, cause you can't really combine events with each other.
