Wherever the menu methods described above allow a coption
, you may apply a value to any of the
option names below by using the option name as a keyword
argument with the desired value. For example, to make a
command's text appear with red letters, use “foreground='red'
” as an option to the
add_command
method call.

actually implement the accelerator; use a
keystroke binding to do that.
