speedbar-mode-functions-list

speedbar-mode-functions-list is a variable defined in `speedbar.el'.
Its value is shown below.

Documentation:
List of function tables to use for different major display modes.
It is not necessary to define any functions for a specialized mode.
This just provides a simple way of adding lots of customizations.
Each sublist is of the form:
("NAME" (FUNCTIONSYMBOL . REPLACEMENTFUNCTION) ...)
Where NAME is the name of the specialized mode. The rest of the list
is a set of dotted pairs of the form FUNCTIONSYMBOL, which is the name
of a function you would like to replace, and REPLACEMENTFUNCTION,
which is a function you can call instead. Not all functions can be
replaced this way. Replaceable functions must provide that
functionality individually.
