To create a Shortcut:
In the application view of your project, click the Documents tab.
In the table pane, select the file for which you want to create a shortcut.
Click in the
Edit
button,
and from the drop-down menu click Create
Shortcut.
In the Create Shortcut dialog box, type:
The name for the shortcut
A description of the shortcut (optional)
Click Browse to select the project where you want to place the shortcut. After you have selected the project, click Finish in the Choose a Project dialog box.
Click Browse to select the folder where you want to place the shortcut. After you have selected the folder, click Finish in the Choose a Folder dialog box.
