Moving around icons in the Dock is a breeze, because you can just drag them around and in and out of the Dock if necessary. The same can be done with the Menu Bar. You can remove and rearrange icons in the Menu Bar by holding down the Command key and clicking the icon you wish to remove or rearrange. Then, if you want to remove it, simply drag the icon off the Menu Bar. If you want to put it somewhere else on the Menu Bar, drag it around until its in your desired location, just like in the Dock.
(Note: I have Leopard 10.5.1, I have not tried this with any other build of Leopard or past OS’s)
* note from James – this also worked in Tiger, possibly Panther
