Blue macros and hotbar hot keys
 

I think these are disabled on Blue but just double checking:

Can you show a 2nd hot bar?

Can you do things like "/pause 10, /corpse" in macros?

Can you bind a key to page 2 buttons on they hotbar?

Multiple hotbars were too far outside the p99 timeline, even for blue. They're not classic.
you can do /pause 10, /corpse on a single line in a macro
By default page 2 on hotbar1 is Shift+2
