I just intalled Displayfusion and I like the extensive functionality. However, I can't figure out if it is possible to control my second monitor, while I'll continue to type in a Word document on my primary monitor. Often, I have a a pdf or powerpoint file opened on my second monitor and it would be awesome if I could skip to the next page or slide, all while being able to continue to type in a Word document on my primary screen without having to use my mouse.
This wouldn't really be possible, no. PowerPoint would need to have focus in order to send keyboard input to it, which would take the focus off of Word. You can do it with a couple of keyboard shortcuts though. When you're in your Word doc, just press Alt+Tab once to switch to PowerPoint, press your next key, then press Alt+Tab to flip back to Word again. Saves having to use the mouse at least
