Macro to use trinket and weapon together?

I have a trinket and a weapon that both have an one use ability and I’d like to macro them together if possible. I’ve tried the following but only the trinket fires off:

/use 13
/use 16

I believe those are the correct commands to use each item slot but they don’t both go off, so I wondered if there was something similar to /castsequence for items?

If not, there’s always a macro that uses each item on left and right clicks.

Yup, /castsequence.

#showtooltip
/castsequence 13, 16

Thanks… I really should have been able to figure that out myself though. :sweat_smile:
