Re: finger-pointer curser as default for mouse-face text

[Richard Stallman]

    : Measure the time between the mouse-1 down event and the up event, and
    : if it less than 300 ms (configurable), follow the link, else do what
    : mouse-1 normally does.

    On ms windows this is again a setting in the registry.

I am not quite sure what "this" refers to here.  What is the
setting in the registry, and what does its value normally mean?
Does MS Windows have this feature?
