Indeed, going to a one-button-and-drag interface would seriously
reduce the effectiveness of the tool.  The operation described above,
where one is trying to precisely draw a large rectangle is used quite
frequently in large designs (at least, by me).  I often find myself
defining large arrays of structures, and thus have three windows on
my screen - one focused on the lower left hand corner, to make sure
I start the rectangle in the right place, one in the upper right hand
corner of the structure, to make sure I close the rectangle in the correct
place, and a "global" window, so that I can see the results of my
array construction.  Because most of the time you want the structures
to overlap, using an 'f' to put a square around the entire structure
is not effective.

Of course, I have personal prejudices against the single-button mice,
too.  It has always seemed to me that arguing that a mouse should have
a single button was equivalent to saying that a keyboard should have half the
keys - one can generate a 'c' by double-clicking the 'd'.  It seems
to me that any I/O device should have as many different inputs as can
be easily managed - there are obvious problems with putting more than
three buttons on a mouse, but I see no point in having less.  Anyway,
that's just my personal opinion, and really has nothing to do with the
argument above except that I needed enough text here so that rn would
not reject this posting.
