We have for macro buttons all mine are just taken up with just general chat I know that we can use /tell bodhii for example to talk to a player but is there anymore of these that we can use to for example to switch targets or change equiptment?

For example im in pvp on archer I use /equip armor Sniper's Croc Scale Leather I then have used up most of my mana so I use /equip armor Mamboza's Croc Scale Leather to fill my mana up quicker.
