+==== Hiding particular symbols from legend ====
+Sometimes you might want to hide just one particular symbol from the legend. \\
+This is as simple as setting the legend text for the symbol to an empty string, "" \\
+This is done within the thconfig file.
+eg
+  text en "line border:visible" ""
+  text en "line border:temporary" ""
+  text en "line border:presumed" ""
+With this example, none of these borders will appear in the legend, even if these lines are used in the drawing.
