One other possible use of this facility: If you like to take screenshots, try setting a shortcut to scrot in the same manner. Now when you press the keyboard shortcut you chose, a screenshot will be saved, probably in your home directory. (Try it and report back where the screenshot is saved.)
Mint already has shortcuts set up for taking screenshots:
Print Screen = Take a screenshot
Ctrl + Print Screen = Copy a screenshot to clipboard
Alt + Print Screen = Take a screenshot of the current window
Ctrl + Alt + Print Screen = Copy a screenshot of the current window to the clipboard
Ctrl + Alt + Shift + R = Toggle desktop recording (video will be saved to your Home folder)
Screenshots get saved to ~/Pictures
Also premade scripts courtesy of VV221 that enable easy install of several Windows games on Linux.
I'll add one here (and will gladly edit this if someone can get me a direct link) but there is a FANTASTIC game called Thea
I had forgotten about those, thanks for reminding me... links to them have been added.
