Bare with me. I have a Logitech Mx500 mouse. It has two extra buttons on it in the thumb area. My main objective is to be able to just press one of these two buttons and have the OBJECT SNAP CURSOR MENU pop up (exactly the same as holding shift and pressing the right button). Now, with the mouse software that is installed, I can set the button to the F12 key which is currently not in use by AutoCad. So, the idea is to set the OBJECT SNAP CURSOR MENU to the F12 key. How do you do that? I tried putting: ["F12"]$P0=SNAP $p0=* in the accelerators section of the ACAD.MNS file but, when I press F12 it says: Command: $P0=SNAP Unknown command "$P0=SNAP". Press F1 for help. Command: $p0=* Unknown command "$P0=*". Press F1 for help. Can someone help?
