was wondering if some one coud explane how to st macros to click action bar buttons that are on other action bars than the primary bar

i realise this is an oddball question but iv been looking and cant find the command for the other bars

This was explicitly disabled in the macro system as of 11.0.0.

In the initial alpha build of 11.0.0, the “macrotext” secure attribute appears to have been removed from the macro action available to secure action buttons.

Macro chaining is dead.
