Does anyone know how to change the command of Perpendicular of the OSNAP override?I'm tired of typing 'per' when i want to perpendicular my line to another distant line. I want to change it to 'er'... involved changing the CUI file??Thanks!

You can set PER as a persistent osnap - so you don't need to enter anything. If you have a newer version of AutoCAD you can also assign PER to one of the key overrides (with the CUI command).
