# pylint: disable=C0112,R0903

"""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 delimiter (; 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)
