I'm sure most beta players are aware already, but without the ability to sort your inventory it can be a hassle to go switching around classes. This is especially true if you're like me and like to dabble in a bit of everything and do virtually all of the leve quests available to you.
Basically, use your macros to switch quickly between classes. Here is an example of a simple macro:
/equip main "Weathered Pickaxe"
/equip sub "Bronze Sledgehammer"
That macro will switch your gear over to make you a Miner. I personally am playing Conjurer and Thaumaturge right now, but I went ahead and bought all the basic tools for crafting and gathering. So I have a Conjurer, Thaumaturge, and DoL/DoH macros to switch around with ease.
For something like a Conjurer macro, you can get a little more advanced and have it equip specific spells and abilities. For this you use:
/eaction 2 "Cure" main
What this does is it sets your Cure spells in the 2nd slot. Your basic attack will always be set in the first slot and you do not need to macro that. Anyway, go ahead and use this maintenance time to think about organizing macros. You can even type them up on notepad now and copy/paste them over into the game if you're using the FFXIV Windower. I'm sure there are other uses for macros, but I thought these were basic entry level ones that players should know about. Enjoy!
Edit: This is a good summation of the macro system for any bored people wanting a good read:
