Pitch angle question

[Chaos.]

I've read somewhere that in order to make a doodad unside down, you have to make the pitch angle a negative number. So how do you change the pitch angle to make it a negative number? It wont let me go below 0.

Press in Shift while double clicking on the value, then you'll notice your able to make negative numbers, this also goes for the other one, Roll Angle.

Only problem is that using such method decoration sometimes impossible to see. I mean it dissapears from screen although it is supposed to be there. Fail-safe is to rotate it in Mdlvis or other model editor.
