What's a feature you use a lot on your PC that you think other people probably don't know about?

I'll start - middle click on the refresh button in the browser to duplicate the current tab

@JenMsft Taskbar on the left side of the monitor! It's a way better use of our extra horizontal space since the 4:3 aspect days. Vertical resolution is precious now.

(or at least need to install something like StartAllBack to get that functionality back)
