How do I use macro 1, 2, 3, etc in the same macro?

1 macro says
use version 1 for mythic+
2 says for raiding
3 says for pvp?


Select the macro and hit edit - then look at the configuration tab. The macro will auto switch based on your circumstance.

hows it know when im in world pvp as opposite to matches?

so your saying just hir.the macro amd the macro knows if your pvp, mythic, rading etc?

If you have warmode on its pretty much the same as a battleground

thnx for the help
ill give it a go
