Look at all those OSNAPS available to users in AutoCAD in the Osnap dialogue box. Thirteen of them, plus or minus depending on which version you have.

It would be a lot easier if there were a quick way to set that running Osnap with just a few keys wouldn't it.  Well, hope is on your side.  PostalCAD offers seven variations to setting a single running OSNAP.  This following list shows the keyboard shortcuts and their respective operations:

OAI - Turns on just the APPARENT INTERSECTION running OSNAP.

OC - Turns on just the CENTER running OSNAP.

OE - Turns on just the APPARENT ENDPOINT running OSNAP.

OIN - Turns on just the INSERTION running OSNAP.

OI - Turns on just the INTERSECTION running OSNAP.

OM - Turns on just the MIDPOINT running OSNAP.

OQ - Turns on just the QUADRANT running OSNAP.

A quick way to turn off the running OSNAPs using a PostalCAD shortcut is to enter OO (using the letter O not  the number zero) on the command line.  

The AutoCAD version uses the F3 key to toggle it On or Off also.
