When editing in PowerPoint lately (using 2010, but occurs in other versions I believe), I have often pasted in large images that are larger than the screen. I'll then scroll down (with my trackpad) to try to get to the bottom of the image to resize/crop the image to the appropriate slide. However, I end up scrolling a little bit too far which causes PowerPoint to progress to the next slide. When I go back to the previous slide, the screen is not all the way at the bottom (usually 1 or 2 scroll-lengths away), leading me to try again, and usually progress to the next slide again. Comedy ensues.
Is there any hope (other than training my muscle memory to go manually click on scroll down arrow, scrolling down one click at at time, the technique I fall back on after overshooting 3 or 4 times)? Any of these could solve the issue:
Configuring PowerPoint to not scroll to the next slide when using the mouse wheel scroll action (thus limiting the scrolling to only the current slide)
Learning a keyboard shortcut for PowerPoint to scroll to the bottom of the content on the slide (which may be below the bottom of the viewable slide)
Have PowerPoint automatically resize images to fit on the page upon pasting, or knowing a keyboard shortcut to auto resize the selected image to the bounds of the slide.
Some other action that you've thought of that I have not.
