I've been using Sonar since X1 through Splat. Recently I purchased a Corsair Gaming Mouse for Studio One with 12 X 3 programmable buttons. I was going to program some of the buttons to bring up the various tools and found accidently that if you push the scroll wheel, the tool menu appeared and you could select any of the 15 tools w/o dragging the cursor to the menu bar, or reaching over for the number keys.
I tried this with a plain vanilla, wood burning mouse and it did the same thing. I also tried it in Sonar and it also brought up the tool menu. If everyone else already knew this, then I must have been living under a rock. (Although I do play some). I googled it and it did not show up.
So I hope maybe this tip might help somebody else.
