Macro

The macro function is considerably more complex than most regular functions. Macros can string several different commands together into one command, allowing you to instantly perform several actions in a row. The syntax is as follows:

/macro [macro name] /[command 1] ; /[command 2] ; /[etc.]

This creates a macro command in the form /[macro name] that will execute [command 1] and [command 2] and any other commands in order, and also creates a hotbar button for quick use. As an example, if a player wanted to both say "Whoa" and use the /whoa emote simultaneously, the following macro could be formed:

/macro saywhoa /whoa ; /say Whoa!

To use this macro, the player only has to type /saywhoa in order to run it, or click on the hotbar button. Removing the button from the hotbar deletes the macro. As a second example, if a player wanted to clap, cheer, then whistle, the following macro could be formed:

/macro woohoo /clap ; /cheer ; /whistle

It would then be able to be run by typing /woohoo into the chat window.
