How to call built-in character macro from standard macro

I've not been able to find this in the forums or documentation. Say I have a character named Gnoll, serving as a generic Gnoll.  Say I'm using the DnD 5th Edition Character Sheet.  The gnoll character sheet a weapon Spear, which has an associated built-in Attack macro.  Say I want my Gnoll token to have a drop-down Attack With Spear macro.  First step is to create an Attack With Spear macro, which wants to call the built-in spear Attack macro. What is the proper syntax to call the built-in Attack macro from my custom macro?   Thanks for your time and attention.  If this has already been answered please link to the answer.   P.s.  Is there a scripting UI technique that helps?

Here's the appropriate documentation for DnD5e Character Sheet and DnD5e Shaped Character Sheet .

Bruce Are you using the NPC sheet for the Gnoll, if you are I think you need this. But you also need to fill out the action part of the NPC sheet. Type Macro Action 1 repeating_actions_0_action Action 2 repeating_actions_1_action Action 3 repeating_actions_2_action continues in sequence I am trying to do the same thing. Cheers Frank

Bruce Will this help you. @{selected|output_option} &{template:5eDefault} {{action=1}} {{character_name=@{selected|character_name}}} @{selected|show_character_name} {{title=@{selected|repeating_actions_0_name}}} {{action_type=@{selected|repeating_actions_0_type}}} @{selected|repeating_actions_0_macro_options} Cheers Frank
