I want to have the label from the command that is being used. Compare it to PRCommandWidget it displays the labels of all available commands. I want to have to same as value link.

+value:commands+ displays all the available value links because it 
displays all selectors of methods that have the proper <pragma> in them. 
You're talking about displaying the options available for a specific 
value link and there's no built-in mechanism for that. You'd have to 
provide it yourself. You could request all parameters for +value:xxx+ 
that was passed to the >>xxxIn:contents      method, but that would only 
give you the parameters/commands that are specified in the text of the 
link. If you want to provide a list of all possible options, you'll have 
to define one yourself:

+value:myValueLink|command=displayAll+    and from inside method 
 >>myValueLink:contents, you'd return a list of all the options you 
defined within >>myValueLink:contents.
