If you are looking for a way to launch/trigger KM macros by name, then I'd suggest:
- Use the built-in KM Action Trigger Macro by Name action
OR, even better - 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.
