## Which Function Mode

Which Function mode is a minor mode that displays the current function name in the mode line, as you move around in a buffer.

To enable (or disable) Which Function mode, use the command `M-x which-function-mode`. This command is global; it applies to all buffers, both existing ones and those yet to be created. However, this only affects certain major modes, those listed in the value of `which-func-modes`. (If the value is `t`, then Which Function mode applies to all major modes that know how to support it--which are the major modes that support Imenu.)
