benpatient said:My question about Mighty Mouse is this: What if I only want to scroll vertically? A lot of documents are wider than my screen (1600 pixels, as it happens), and when I scroll, I only want to scroll one way...vertically. Can you disable the horizontal scrolling, or make it necessary to hold down a key to alternate to horizontal scroll (which is what a normal scroll mouse does in most programs when you hold down Option? If not, this is like a really expensive headache, as far as I can tell.
There is an option to turn on and off a direction, but there doesn't seem to be a "hot-modifier key" option to toggle the settings.
I have played around with a Photoshop doc that was zoomed in, the vertical and horizontal scrolling is very intuitive, so accidental scrolling one way or the other isn't as likely as one might suspect.
