Keyboard shortcut Safari and Keyboard Maestro "Add to DT"

To change Safari’s “command s” to add to DT instead of saving a webarchive:
Remap “command s” to something else like “command option s” using the “keyboard” Apple system preference pane.
Use Keyboard Maestro to create “command s” as the hot key for the menu item “Add to DT” under file/share/Add to DT
