If you click with mouse-1 onto a display string it will reveal its
content.  As soon as the cursor leaves the content, it will collapse
and show the display string again.

mouse-2 would destroy the respective overlay and thereby make its
content visible permanently.  This would be the same as the "Remove"
option in preview-latex's context menus.

Ah, now I see.  I haven't recognized that you had to click onto the
image when the content is shown.

Anyway, with TeX-fold there is no need for a placeholder which serves
as a button and you don't have to look after collapsing the content,
it just happens automatically when you leave the area.

Why not?  If I click onto the start of a display string with mouse-1,
keep the button pressed and drag the pointer to the end of the display
string until all of it is highlighted, I can paste its content (not
the display string itself) with mouse-2 afterwards into the buffer.
The same behavior I get with preview-latex and its images.  Unless you
meant something else, I cannot see a difference here.
