A pretty simple one. It lets you do just one thing: quickly change the destination folder for the screenshots.
It does not intercept and move the screenshots from the Desktop to another folder, it changes the system’s screencapture preference with the defaults write com.apple.screencapture locationcommand.
The destination preference will apply to all “system” screenshots (⇧⌘3 etc.) and will be persistent until you change it again.
You can use this macro also as a boilerplate for other defaults write macros.

As you may have noticed I’m currently on the replace-all-user-prompts-with-a-shiny-new-HTML-user-prompt trip
So, also this little macro has a nice new HTML interface now:
This is a relatively late love because, since I’m not into javascript at all, I was intimidated first. But with the help of this forum everything is doable
You should enjoy the next version then, I've added a few more ways to communicate back and forth between the Custom HTML Prompt and Keyboard Maestro which should enable even more fun.
If you are using Sierra (10.12) please redownload the updated macro from the download link in the original post. (It should work with both El Capitan and Sierra.)
I just used it (thanks for the reminder that it exists!) as I had to reinstall everything a few weeks ago and my system screenshots were still going to the Desktop folder. (I didn't notice this before because I do 95% of my screenshots with Shottr, a truly amazing screenshot tool and one of the most well-designed and thought-out little apps I know).
