Yeah, for macro use remember these:

Abilities:
/ma "<spell>" <target> (Magic Ability)
/ws "<skill>" <target> (Weapon Skill)
/ra <target> (Ranged Attack)

Channels:
/p "<message>" (Party Channel, party members hear only)
/l "<message>" (Linkshell Channel, Linkshell members hear only)
/s "<message>" (Say Channel, anyone within a certain radius hears)
/sh "<message>" (Shout Channel, anyone in same zone hears)
/t <target> "<message>" (Tell Channel, target hears only)

As far as <target> and how you fill it in depending were you use and for purpose you have options.

<stpc> (Select Target Player Character)
<stnpc> (Select Target Non-Player Character)
<t> (Select Target, if a target is currently selected that's the one used)
<stlast> (Select Target Last, can be used in conjunction with stpc and stnpc to create a second targeting for multi-function purpose)
<bt> (Battle Target, target is whatever you or party has already engaged and claimed)

For some macro setups you may see them not work as intended or give errors, try re-arranging the sequence it does if it is possible. If re-arranging does not work then you can add in the command /wait <time>, <time> has a max count of only 60 seconds.

There's a lot more you can do with the macro's but that right there should be a decent start.
