Request: Cast lvl1 spells with lvl3 magic using ctrl+shift?

[Shadowdrake]

See title. I was just wondering how easy it would be to make a mod to be able to cast spells at lvl1 if you already have the spell at lvl3. Any ideas?

[Metathron]

Huh? Can't you do that already with ctrl/shift? :confused:

[Elwin]

its alreadz in game so why implement a mod for it?

[Shadowdrake]

is it? That's weird; it doesn't work for me. I thought it might be handy so I requested a mod for it; o.O sorry.
Do you know in which version this appeared?
