Indeed. The single mouse button on a Mac doesn't lead to a more

"Shift-Ctrl-leg-in-the-air-Click", IYSWIM.

At this point I am reminded of an American car I rented a few years
ago. It happened that I had some time to kill while sitting in the
car, so I started reading the manual. I learned that one of the car's
fancier features -- which I will not explain here -- had four different
settings, to be selected according to the owner's preference.

The thing is that the designers must have wanted to avoid the expense
of providing a separate four-position switch for a feature whose setting
would hardly ever be changed once it was set initially (probably by the
dealer). But they also wanted it to be impossible to change the setting
by accident in normal driving.

So what you had to do to advance the option setting by N steps in its
cycle was this, starting with the engine stopped:

[1] Turn the ignition key to the "on" position (not "start").
Then:
[2] With your left hand (driver's seat is on the left, remember),
hold down the door-lock button in the armrest.
[3] With your foot, hold down the brake pedal.
And simultaneously:
[4] With your right hand, move the automatic transmission out of
Park and back into Park -- N+1 times!

At least, that's what it said in the manual. I didn't actually try it.
I didn't try pressing Control-Alt-Delete either. :-)
