The TRIM command extends and trims.

I just tried PERP. Yes, it makes a perpendicular line but it does not snap to the line. For me it didn't even let me specify an endpoint; it created a short line segment that was perpendicular to the specified line.

My recollection of how AutoCAD handles this, from the command line:

L from [click] to PER to [click].
