One of my favorite usability features in Photoshop are the view functions you control with your mouse and a command keys. Especially these:
- space + click and drag = pan image (like smooth “scrolling”)
- ctrl + mouse scroll = zoom
- alt + mouse scroll = scroll horisontally
This tutorial on getting ReSharper keypress (alt+enter) to fix spelling hints in MS Word prompted me to think of other app combos. So the idea is a Chrome or Firefox extension that allows you to easily zoom and pan the website. Kind of how you do it on iPad, you just zoom in and “flow” around the page.
What other navigation or key-combos would you like to see from one app into another?
