To open an object from the desktop background,
double-click on the object. Alternatively, right-click on the object, then
choose Open. When you open an object, the default
action for the object executes. For example, if the object is a text file,
the text file opens in a file manager window. The default actions for file
types are specified in the File Associations
preference
tool.
To execute an action other than the default action for an object, right-click on the object, then choose Open With. Choose an action from the Open With submenu.
The items in the Open With submenu correspond
to the contents of the following parts of the File Associations
preference tool:
Default action drop-down list in the Edit file type dialog
Viewer Component drop-down list in the Edit file type dialog
You can set your preferences in a file manager window so that you click once on a file to execute the default action.
