I understand that MS and Mac desktops have a similar feature.  To
select a set of 15 items, the user clicks to select the first item,
and then control-clicks to select the subsequent 14.  So the only
difference between single and double click activations is whether the
first item is selected using click, or control-click.  To my mind, the
"click to activate, control-click to select" approach seems more
consistant and easier to use for the common case of object activation.

Yes, as John Sullivan has pointed out, Eazel has done actual user
testing that shows that double-click activation is easier for people
who are new to Gnome to use, and so would be the correct default,
especially for novice users.  I suspect though that they find the
double-click activation more natural because it's what they are used
to on MS and Mac platforms, rather than due to any innate superiority.

I think that there's room for improvement here, at least for people
willing to try something different than what MS provides.  Something
like what was described for Acorn-OS seems like a good start: clicking
with mouse button 1 activates, clicking with mouse button 2 selects,
and clicking with mouse button 3 brings up a menu of preferences or
actions.  

This could be used to provide a set of actions that would be similar
under a wide range of situations.  For example:

- On a desktop icon:
    . Button1 activates the program or document;
    . Button2 toggles between selecting and deselecting the icon;
    . Button3 activates an object settings or preferences menu.

- On a menu item:
    . Button1 activates the program or submenu;
    . Button2 toggles between selecting and deselecting the menu item,
      allowing one or more menu items to be copied to the desktop or to
      the favorites menu;
    . Button3 activates an object settings or preferences menu for the
      program or menu item.

- On a hyperlink or underlined URL in a terminal:
    . Button1 activates the link as usual;
    . Button2 selects or deselects the link, so the URL can be copied
      into a document or placed on the desktop;
    . Button3 brings up a menu of things that you might want to do
      with a web page -- edit it, render it, print it, mail it to a
      friend, or whatever.

This pattern is easy to use, easy to learn, and easy to extrapolate
into new usages.  It also avoids the RSI-inducing need to double click
to perform the most common action of activating a desktop object.
