Adding macros to Apple LaunchPad

If you are looking for a way to launch/trigger KM macros by name, then I'd suggest:

  1. Use the built-in KM Action Trigger Macro by Name action
    OR, even better
  2. MACRO: Execute Macro by Name (Spotlight) by @DanThomas

For launching apps, web pages, files, folders, KM macros, and much more, I'd suggest:
LaunchBar.

LB even includes custom actions that you can write in AppleScript, JavaScript, and other languages to do whatever you want.
Highly recommended.
