+
+"""Shows a widget per user-defined shortcut and allows to define the behaviour
+when clicking on it.
+
+For more than one shortcut, the commands and labels are strings separated by
+a demiliter (; semicolon by default).
+
+For example in order to create two shortcuts labeled A and B with commands
+cmdA and cmdB you could do:
+
+ ./bumblebee-status -m shortcut -p shortcut.cmd="ls;ps" shortcut.label="A;B"
+
+Parameters:
+    * shortcut.cmds  : List of commands to execute
+    * shortcut.labels: List of widgets' labels (text)
+    * shortcut.delim : Commands and labels delimiter (; semicolon by default)
