https://www.curseforge.com/minecraft/mc-mods/command-macros It is a macro mod to bind your command. But it's not including auto-repeat.
I’m using this one https://www.curseforge.com/minecraft/mc-mods/command-macros for keybinding commands
I've searched around about a month ago for 1.15.2 macro mods and the one linked above is the only one i could find
@zr2002 are you trying to update macromod or make your own? or are you just making common macros people had in macromod?
I'm going to make a thread about it shortly. I think what I'm going to do is make common macros that people used to have (any sort of display labels, automatic trade ads, things like that) where users can request whatever sort of mod/macro that they want (assuming it's legal on ECC of course).
