 ====== Signal Names ======
-/Signal_Names
+This is a common parameter in pipeline commands, allowing the user to specify which specific signals to be evaluated as input. Signal names are the third (bottom) level of the [[visual3d:documentation:visual3d_signal_types:data_tree|data tree]] hierarchy.
-or
-/SIGNAL_NAMES
-The names of the signals used by the Pipeline Command.
-The + symbol is used as a delimiter for multiple entries.
+The parameter will appear in commands as /Signal_Names or /SIGNAL_NAMES.
-For example, to specify the three signals RFT1, RFT2, and RFT3
+===== Multiple Input =====
+The + symbol is used as a delimiter for multiple entries. For example, to specify the three signals RFT1, RFT2, and RFT3:
+<code>
 /Signal_Names=RFT1+RFT2+RFT3
-Many commands allow Signal_Names to be blank
+</code>
+===== Empty Input =====
+Some commands allow empty input for this parameter, for example:
+<code>
 /Signal_Names=
-In the cases that this is allowed, this indicates that Visual3D should use all signals of the specified [[Visual3D:Documentation:Pipeline:General_Information:Signal_Types|Signal_Types]]
+</code>
+In these cases, this indicates that Visual3D should use all signals of the specified [[Visual3D:Documentation:Pipeline:General_Information:Signal_Types|signal type]] (and, if specified, [[visual3d:documentation:pipeline:general_information:signal_folder|signal folders]]).
+===== See Also =====
+The Signal_Type parameter is often accompanied by two other parameters:
+  * [[visual3d:documentation:pipeline:general_information:signal_types|Signal_Types]]
+  * [[visual3d:documentation:pipeline:general_information:signal_folder|Signal_Folder]]
+Together these three parameters represent the application-wide [[visual3d:documentation:visual3d_signal_types:data_tree_syntax|data tree syntax]].
