Updates for new Custom Shortcuts Dialog
The Preset dialog isn't discussed in the user guide (and I think I'm out of time to write a section for it). So I fixed a typo I found in the presets section and added a section to discuss the custom shortcuts dialog. The image I added doesn't have the same resolution as the others, but I'm not sure how to take a screenshot with that higher resolution... so that will probably need fixing. I could fix it by rescaling, but it would probably still be blurry.
