How do I adjust the sensitivity of zooming and panning? Recently when I was using Blender, I accidentally did some sort of keystroke that messed up my navigation settings. The sensitivity of zooming, panning, and orbiting was knocked to almost zero, and I could not move around the scene at all. I did some research to find out how to fix it, and one thread led me to the Navigation preferences pane in Blender. However, I was only able to adjust the orbiting sensitivity, as I saw no adjustments to zoom or pan sensitivity.
Here's a screenshot of my navigation settings:

Any help would be greatly appreciated.
I hate these useless moderators.  The scroll sensitivity is a windows issue, not necessarily blender.  Google answered my question at the tip top of my search:
Change Mouse Scroll Speed in Windows 10
Open the Settings app.
Go to Devices -&gt; Mouse.
On the right, select Multiple lines at a time under Roll the mouse wheel to scroll.
Adjust the slider position to specify the number of lines between 1 to 100 lines at a time.
