On GNOME 2 and KDE, by default, clicking anywhere on a window while pressing the Alt key will move the window. Because the Alt key is used as a modifier for many drawing and animation tools in Harmony, it is highly recommended to configure your desktop environment to use the Super key (ie: The Windows Logo key, on many keyboards) for this purpose instead.
In the GNOME top menu, select System > Preferences > Windows.
The Window Preferences dialog appears.
- In the Movement Key section, select Super (or "Windows Logo")
- Click on Close.
In the KDE menu, select Computer > System Settings.
- In the System Settings window, select the Windows Behavior icon.
- Select the Window Actions tab.
- In the Modifier Key dropdown, select Meta.
- Click on Apply.
