Depending on what OSNAPS you currently have turned on, you can simply cycle through them without having to move your cursor over the exact snap that you need.
(This is really helpful in your drawing is cluttered and you want to snap to the correct object)
In the example below, I have the following OSNAPS turned on:
EndPoint, MidPoint, Center, & Intersection
- I started a line and then hovered my cursor over an object
- I then hit the TAB button until I saw the certain OSNAP over the object that I wanted to snap to.
- I then left-click the mouse to connect the line to that snap.
