Hi there!
I am looking for a way to quickly open System Settings/Displays/Arrange, or at least Settings/Displays. Any advice? Ideally I'd like to use my Magic Keyboard Brightness key (F1). I can''t figure out how to do it. 
Here's a screenshot...
Thanks!

Probably there is some Apple Script. Otherwise just automate what you do manually. Click "Arrange" probably works best with image recognition.
You can open the displays preferences using this terminal command
open /System/Library/PreferencePanes/Displays.prefPane
or alternatively
open x-apple.systempreferences:com.apple.preference.displays
However I don't think there is currently a way to directly access the arrange modal ;-(
Awesome thanks! That worked.
I used non-blocking, is that ok?
Just came here to say that I was looking for the same thing and that I'm still amazed by all the functionality that BetterTouchTool offers. It's almost limitless. Thank you Andreas! I cannot praise BetterTouchTool enough. The first app I install on a brand new Mac.
EDIT: Yes, Craig, async is probably better. Sync might be better if you need to execute a few commands one after another and you need to wait for the previous command to finish to execute the next one.
