How do you scale in a 2d fashion?

well- the s key does scale- in a uniform fashion. but then if you click the middle mouse button while scaling it constrains to the axis you started moving in. This way you can isolate x, y and z axis. I guess this is 1d scaling. you could do it twice in two axis for 2d, i guess.

You can also ofcourse pop up the ‘n’ menu, and manually fill in values.

but this ain’t as cool as the way bassaminator told you
