How to show windows only from the current workspace in Unity switcher?

For 12.04

This is the default behavior now!

For 11.10:

This isn't currently possible, however there is a workaround that you can set that will display the applications in your current workspace first, which means you can Alt-Tab to it quickly without having to go through applications in your other workspaces. Though this doesn't limit the switcher to the current desktop but it at least puts the apps on that desktop first:

First:

1. Install the CompizConfig Settings Manager (CCSM).
2. Then go to the Switcher tab and select "Bias alt-tab sorting ...." and make sure you check the box.

• How can I configure Unity?

You may not be able to use the current Alt+Tab switcher, but there are other ones accessible from compiz.

Try installing CompizConfigSettingsManager (package name: compizconfig-settings-manger). From there you can disable the Alt+Tab switcher from the Unity plugin.

After that you can enable one of the other window switcher (Application-Switcher, Static Application-Switcher, Shift-Switcher)

I chose to change the keybindings on Static Application Switcher to be Super+Tab

Hope that helps!
