I'd rather not waste bar space and keybindings on such macros.

Things I tend to type in broadcast are:
Whispering someone for raid invites.
Emotes.
Hearthstone.
Any new companion or mount that I got for everyone.
Summoning of companions and mounts that I don't use regularly. (any companion really, since I don't use them regularly)
Quest items. (could use the jamba item bar, but I have not found any keybindings I'd like to spare for that purpose yet)
Other items that I want to use on everyone on occasion, such as the commendations of service this most recent patch.
For teams with multiple of the same class, equipping a new item they all got.
