Now there is another really cool thing that can be done with Signs, and that has to do with Macros! Now there are many players that don't know this, but if you check your various menus (usually the Main Menu where you can find options to customize UI, change system and character configurations, etc.), you will find a menu to customize macros.

Now with Macros, you can do things like /ac "True Strike" <t>, which will allow a character that has True Strike to use it on the target. You can also have things like /ac "Aero" <tt>, which will cast Aero on your target's target (useful for healers). But did you know that you can also use Signs in this way too? For example, you are a Summoner or a Scholar and you REALLY like using your DoTs. You can use /ac "Bio II" <attack2>. Doing that will actually cause your Summoner or Scholar to use Bio II on the enemy marked with the "Attack 2" sign. Really cool, right?
