Mouse scrolling changed from moving page up and down to enlarging and decreasing text size

[Sweetpeasal]

When scrolling the wheel on the mouse, it suddenly changed to making the text larger or smaller when it used to just move the page up and down. Something changed. How do I get it back to just moving the page up and down and not altering text size. What did I hit to make it change like this. Would love to know so I won't do it again. This is maddening.

Make sure your CTRL isn't stuck. That happens to me constantly.


EDIT: It might be another key depending on your region I suppose, check ALT, CTRL and SHIFT.
