Fix #5: CTRL or SHIFT key stuck
If you’re pressing the CTRL key while rolling your mouse wheel, you won’t be able to vertically scroll in Excel.
What this does is Zoom in and out in your Excel spreadsheet 🔍
If you want to scroll vertically with the mouse wheel, simply release the Ctrl key on your keyboard. Or make sure it isn’t stuck 👍
But maybe it’s not the Ctrl key that was stuck but the Shift key.
If the SHIFT key is stuck, the vertical scroll bar will definitely not work.
Again, simply release the SHIFT key from the stuck and you will be able to scroll vertically 😊
