Hi, @Joel. Thanks for sharing your macro!
On my system, the esc is unnecessary. If the CH is visible, the Activate Clipboard History Switcher action closes it.
Also, here's a tip when sharing macros: if you set the editor to a more narrow width, the macro images will be much more readable. For example, with what you shared above:
On my macBook Pro, before I share anything I normally set the Keyboard Maestro editor to the right half of the display.
If it's not already there, I need to add that tip to this post: Entering and Enhancing Forum Posts
