Key modifiers for relative draggable values

[positlabs]

This would be nice to have for Vector or Number inputs.

Shift+drag: change by intervals of 10
drag: change by intervals of 1
Alt+drag: change by intervals of .1
Alt+Shift+drag: change by intervals of .01

What do you think?

yes why not
for the moment there is no key input but is possible
for the moment is like slide { step:1 }
