You can configure Spaces by visiting the Dashboard and Exposé preference pane in Mac OS X Leopard’s System Preferences. There you can create rows and columns and arrange your Spaces anyway you like, plus assign what function keys you want to control them. You can also lock specific apps to specific Spaces, so you’ll always know their locations.
You might want to create a Space for work, one for home, maybe one for Internet; it’s up to you. With the click a function key, you can drag all your application windows onto different Spaces. Create a communication Space for iChat and Mail. Organizing within Spaces is as easy as drag and drop and you can even rearrange the Spaces themselves the same way – every application window within the Space you’re moving goes along with that Space as you drag and drop it.
When you’re working in one Space and you want to move to another, you can get an Exposé-like overview of all your Spaces, or just toggle between them using keyboard commands. The Mac OS X Leopard Dock is integrated with Spaces, so when you click on an icon on the Dock, Leopard takes you right to the Space (or Spaces) where you have that particular app open.
