 # kwin-screen-shortcuts
-KWin script for consistently ordered screen shortcuts
+KWin provides shortcuts to send windows to specific screens ("Window to Screen
+N") and to set focus on specific screens when "Separate screen focus" is enabled
+("Switch to Screen N"). However, the ordering of the screens is not predictable
+or consistent across different screen configurations.
+
+This KWin script adds shortcuts with the same name and functionality, but with
+predictable screen ordering from left to right. So no matter what your screen
+configuration is, triggering "Window to Screen 0" will always send to window to
+the leftmost screen.
+
+Ultimately, I think this should be fixed in KWin, but for now a script does the
+trick.
