No. However, if you want to assign the Ctrl+- shortcut key for removing the object code, then you can manually assign it by changing the key binding. For more information on how to assign or change a key binding, see How can I change a key binding?
When you change the key binding, a dialog box appears asking you which project you want to clean, and if you want to automatically start the build thereafter. If you do not want this dialog box to appear, then you can select the Build Automatically checkbox under Window > Preferences > General > Workspace Settings .
