Selection
Selection
SA follows the Action-Object selection paradigm when it comes to issuing menu commands. This implies you first choose a command or operation, and then select the items to apply to the operation. Some operations may need multiple selection steps. When selecting an object, it will change to the selected highlight color and its listing in the tree will become bold blue.
When an operation requires a user to make a selection, a selection prompt will appear. You can then select entities visually in the graphical view.
The entities that you will be prompted to select will depend on the selected command (one of the benefits of the Action-Object paradigm). SA will filter entity types for you, so that if you are prompted to select points, you will only be allowed to select points—not instruments or objects.
To Abort a Command and Exit the Selection Mode:
-
Press the Esc key. The selection prompt will disappear and the command will be cancelled.
In many commands, the prompt permits you to select more than one item—usually as many items as desired. You can continue to select items using the selection methods below until satisfied, at which time you must indicate to the prompt that you are finished selecting items.
To Complete Selection:
-
Press the Enter key
.
There are several ways to make selections in SA:
-
Graphically. Pick items directly in the graphical view.
-
Treebar Selection. Pick items using the tree, using a double click to select the item.
-
F2 or Filtered Selection. Pick items from a filtered list. This filtered selection can either be performed as part of the SA tree bar when Tree Selection is enabled in the User Options or by pressing the F2 key to open a separate dialog window.
The F2 selection also provides more advanced filter options:
-
Wildcard Selection. Pick items based on naming criteria using wildcards.
-
By Color. Pick items based on their color.
-
By Type. Pick items based on their type.
