3ds max highlight selection

[paladin]

Some how, I've hit a key that turned my cursor into a highlighter. I can still work, but when ever I move the cursor over a vertice, edge, or face, it highlights it and if i'm not careful, it will select it. Can someone please help me out? I've looked through all the preferences and and hotkeys and still can't even find out what it is. Here's a screen of what happens.

It turns yellow when I move my cursor over anything.

Lol, nice bird.

In your screenshot you have "preview selection" turned on to Multi, turn it off if you want it to stop.
