I want to toggle my Dock position between the left side and the bottom of the screen, depending on the context I’m in.

To do this…

• Save this Apple Script.

  • tell application “System Events” to tell dock preferences

    • if screen edge is bottom then

      • set screen edge to left

    • else if screen edge is left then

      • set screen edge to bottom

    • end if

  • end tell

• Make a new Keyboard Maestro global macro that runs it.

  • I assigned ⇧⌥⌘D to toggle the Dock.

Here’s a demo in action.
