deleted and re-created at any time.

         This list on the left side of the window allows you to save links to folders that are frequently used. Activating a bookmark will change the active path to that pointed to by the link. To add items to the bookmark list highlight a folder and press Ctrl + B, select “Add bookmark” from the folder's context menu, or drag a folder onto the bookmark list.<?db2html element="br"?>
         The bookmark has a context menu that can be displayed by clicking the right mouse button, or pressing the Menu key when a bookmark has the focus. From the context menu you can edit a bookmark, move it up or down in the list, or remove the bookmark from the list. A bookmark can also be moved by pressing Shift + Up or Shift + Down while it has the focus.
