Holding Alt While Using the Blob Tool

I hold alt while using the blob tool to zoom in and out with the scroll wheel, but when I do it causes problems. 
While using the Blob tool, Is there a way to disable/change what holding alt does? the new versions of illustrator have a really annoying smoothing pop-up that goes directly in the center of my screen where i accidentally click it all the time, and i cant use the blob tool again until i close the file and reopen it.
