I'm no longer playing WoW so I can't actually check any of this:

To make a wholly new bar:
Click on the minimap button, hit the top most popup icon and then right click on one of your (button) bars. There will be an option on the thing that then pops up to create a new bar (it always seems to start off with bar 8 ).

To remove a bar do the same thing with the right clicking it should now have an option to remove bar (if you only have one bar left or the bar is a non-button bar (eg Bag bar) you will only have an option to store the bar.

To set buttons type:

Assuming you have all the bars in the position you want them (you can do this first if you want) you can change the button type to one of several options. The option type allows buttons to do different things. I can't remember all the types, but they include normal buttons (like all the other button bars), macro buttons, slot buttons...

Normal Buttons use them like you use a normal button.

Macro Buttons: Once a button is turned into a macro button you can right click the button to edit a macro, this macro is not a standard game macro though it uses the same scripts, it is parsed differently and so may not work quite the way you'd expect.

Slot buttons: Actually can't remember how they work, but it was something like you can assign a slot (from the character paper doll) and click the button to activate what ever was in the slot (eg a trinket) if you change what was in the slot the button updates.

To change a button type you click on the minimap button till the five little buttons appear and click the button that sort of looks like a key board.

To assign keys to buttons you click the little green key icon (it'll turn red).

If you right click the minimap button you open up the menu, I would suggest turning on Tutorial Messages for the first hour or so, it adds useful comments to all the mouse overs so you can see what most things do.


Hope that helps, and is right... Not been to bed yet and haven't played WoW in over three weeks...
