Each macro consists of two pieces. A trigger, which is typed after a slash (/) to activate the macro, and a result, which is sent to chat once the macro is triggered.

In your macros, you can use a few special symbols. These symbols will be replaced with the words you submit to chat after your trigger. These symbols are $$, which will be replaced with all the words after your trigger, and $N where N is a number, and will be replaced with the Nth word you submit. Additionally, if the number is followed by a dash(-), all words from that position to the end of the string will be used in the replacement.

When submitting chat commands, if you combine them together with the string '&&' between them, you can have chat execute them in order without manual intervention.
