Finding "self explaining" variable names for functions, procedures, widgets and macros is difficult. So if variables are listed with <<.mlink dumpvariables>>, <<.mlink search-variables>> or from the "Variables" tab in the $:/AdvancedSearch, it's not obvious ''how'' they work and how they are defined.

So if variables are listed with <<.mlink dumpvariables>>, <<.mlink search-variables>> or from the "Variables" tab in the $:/AdvancedSearch, it's not obvious ''how'' they work and how they are defined.
The <<.olink variables>> operator returns all "visible" variables from the current context, depending on where the filter run is executed. The <<.olink getvariable>> allows us to return the "text" or the "value" of variables. But this information is not enough to get a good understanding of existing variables.
