Is there a keyboard shortcut to close all open windows?

Question

Is there one just to minimize/maximize all windows?

Is there also one just to close open windows but not the apps your using and vice versa?

Answer 1

To toggle all windows minimize/maximize use WINDOW key(1 between Ctrl and Alt)+D
