    It seems like tooltip-mode is used in several files, so at least that
    function should be mentioned.

The place to document tooltip-mode, if we want to document it,
is the Emacs manual.  It is a user-level command to enable or
disable a user-level feature.

      gdb-ui.el uses
    tooltip-identifier-from-point and gud.el uses tooltip-toggle-gud-tips
    and tooltip-gud-tips-p.

That doesn't necessarily mean they are worth mentioning in the Lisp
Manual.

    Personally, I'd document the following:

    tooltip-frame-parameters, tooltip-hook, tooltip-mode, tooltip-show,
    tooltip-hide, tooltip-identifier-from-point,
    tooltip-show-help-function, tooltip-help-tips.

Why do you think those are worth documenting?
