Sorry about my above reply. It just hit me as to what you may be asking.
You want to use a KM macro to navigate the Trigger by Macro list, correct?
If so, you're right -- doesn't work now.
I no longer use the KM Trigger by Macro.
I use this macro by @DanThomas, which I like much better:
MACRO: Execute Macro by Name (Spotlight)
It does allow you to use KM macros for navigation.
