Written down, because custom keybindings are nice
Kali has user defined print screen. Parrot doesn’t. Let’s fix that without using the internet.
When I first started using Linux, I googled prettymuch everything. These days I find that the fastest answer is probably already on the terminal. To this end, I frequently lean on apropos
; the french term for ‘pertaining to’.

In this situation it yielded exactly what I was looking for. A quick glance at the manpage shows the answer I was looking for in the invocation:
mate-screenshot -a
I navigate to the keyboard shortcuts screen through the gui, and drop in the invocation, and set the keys I want to use. EZPZ, and we’re done.

Very good. Apropos is all the body needs.
