Hi MrBraun, normally this is done in the reverse way for MoI - for normal use leave Object Snaps turned on all the time and if they are getting in your way you can temporarily disable snaps by holding down the Alt key.

It is also possible to set up a keyboard shortcut that will toggle object snap on or off on every keypress (when you type the key, not just hold it down). To do that go to Options > Shortcut keys and add in a new entry, for the command put in this:

script:moi.drawingAids.objectSnap = !moi.drawingAids.objectSnap;
