Now that we've established what a macro is, let's take a look at how to create one. That's the most straightforward way to illustrate some of the macro's basic attributes.
Macros have their own submenu in the Options window. Hit Escape or click the computer icon on the far right of your bottom main menu bar, and then click on the Macros button. The Create Macros window should appear. You can also type "/macro" or simply "/m" to bring up this window.
The window has two tabs, one for general macros and one for character-specific ones. You can have up to 18 general macros that can be accessed by any of your characters, whereas the 18 character-specific macros can only be used by one specific character. The character-specific macro slots are therefore best used for class- or race-specific ability macros. Macro slots can be overwritten at any time, so feel free to experiment with various macros. All macros are stored on your computer: keep this in mind if you play your account on multiple computers.
Under the slots is a window that displays the text of your current macro. A single macro can have up to 255 characters (including spaces) in its text field. A "Change Name/Icon" button is normally under this window, displayed next to the macro's icon. However, if you're creating your first macro, there isn't a "Change Name/Icon" button at the moment because there aren't any macros saved. Let's change that!
