All answers I could quickly find on this topic involve either the tip Molly gave or using an application (or coding it yourself). For example (I haven't tried this), Close All Windows.

Also, by pressing Ctrl + Shift + Esc you get the Windows Task Manager, where you can see all running applications at once (among other things), select them, and End Task them.

Is there a button that closes out all windows at the same time? Tired of closing them all one at a time.
Delete :) Also the pin in the top right of each window keeps that window open when you press delete in case you don't want rid of all of them. Edit: also also, control + clicking the pin means that window will always open pinned by default - useful for things like transparency options that you may always want pinned. More on reddit.com

September 15, 2020 - So it's rare that any keyboard shortcut requires me to hold more than 1 button; I even have some keys assigned to specific shortcuts: cut, copy, paste, select all, switch desktop right/left, etc. I'm my semantic scheme, alt means an alternative of the operation without it, and I use ctrl-shift for controlling the panels and tab bar.
