When I'm working in 2D, and draw a line that is

Is there a certain way I'm supposed to "hover" over some particular point to get it to "snap" me a pp (purple perpendicular) line? Or got a link you can send me to...maybe there's a tutorial that I missed that explains how to do this exact task?

Thanks,

*not*along one of the fixed axes, ie red, blue, green, then I want to draw a line perpendicular to that line, how do I do that? I have seen when SU will "snap" my line*parallel*to another line (I think I know how to make it do this, but it doesn't seem to work every time), and change the line's color to pink/purple, and tell me it's parallel. And I've seen it do the same thing, except that it's*perpendicular*, but I can't figure out exactly what I'm doing to make it give me the perpendicular line.Is there a certain way I'm supposed to "hover" over some particular point to get it to "snap" me a pp (purple perpendicular) line?
