How far back in the history of the Finder or the Mac OS does the
convention go that Click and Drag means Move, and Option-Click and Drag
means Copy?  Is it in the original Mac Graphic Interface handbook and
standards doc?  (I'd look myself, but I'm away from my home library)

If i remember right, it was also in system 6.0.7 and 6.0.8. - Sure
system 7.x has it, 'cause I still use the '7' from time to time...

I believe it does go back to the very beginning.

The original MFS didn't support files with the same name in different
folders, because folders were an entirely fake concept. So it wasn't
there in the first Mac. It could have been any time after HFS was
introduced, though.

It's at least bak to System 6.

But you have it wrong.  click-drag only did a move if you were dealing
with the same drive.  if you clicked and drug to a floppy it always did
a copy, and THAT goes back to System 1.0.  I don't know when the option
drag=move was added, but it was a long time ago.

Drag (at least of text, and at least in the Clarisworks of the
time) was not in 6 - unless I misremember. But you could drag
other objects about like things made with paint tools. I don't
think (ergo) you could option drag anything in 6 but I am not
100% sure.

7 was different and references to this sort of thing is to be
found in eg. The Macintosh Bible 4th Edition.

Probably the most striking thing about ever turning on my old SEs
is the tiny screen. The word processor is about as good as I
would ever want for anything I do. The programming software is
the slackest (greatest error tolerance ever), and therefore
pretty easy going and fun: MS QuickBasic! And it has a better
looking chess program than most I have seen, Sargon IV. And there
is Brickles. I am quite good at Brickles. I doubt it counts for
much these days. Come to think about it, I don't think it counted
for much in those days.

I remember seeing a Mac magazine columnist commenting on an ad for a
keyboard extension cable for a Mac Plus:  "How far away do you want to
sit from 9-inch screen???"

Typo, should be: "do not know"

Oh!  I bet it's sitting in the SPAM box... I'll check in a bit (or
tomorrow morning).  Thanks for notifying me!

Strangely enough, in Lisa OS (at least in the first version), dragging a
file would move it even across volumes--you could drag a file from a
hard drive to a floppy and it would copy the file to the floppy, then
delete it from the hard drive.

To copy a file, you'd click on the file and choose a Copy command from
the File menu. An icon would appear next to the icon of the file you
were copying, and begin blinking black and white. You'd click on the
blinking icon, drag it to wherever you wanted the copy to be, and it'd
copy the file. Incredibly cumbersome from today's perspective.

Still, the Lisa OS did have some nice features. If the operating system
crashed, it would write out the contents of memory and the state of all
the running programs to disk, if you had a hard disk. Then it would
restart, relaunch all the running applications except the one that
crashed, and re-load the contents of RAM, meaning that you would not
lose documents even if they had not been saved. I remember being amazed
the first time I saw it happen.

I actually used a Lisa as my primary computer for several years. Bought
it for $100 from a computer repair shop; the screen kept rolling and
they couldn't fix it. Replaced the potentiometer used for vertical hold
(it used a primitive composite analog video card), and it worked great.
Just recently trashed it when I pulled it out of the closet to fire it
up and discovered the I/O board had corroded to the point where the
computer would no longer boot.

My habit with Windows is to always drag with my right button - because I
never remembered whether the default was Copy or Move.   With OS X, I
left click an item and one of the options is Copy, I don't see an option
for move.

I still don't naturally switch between OS-X and Windows when I need to
switch CTL- and Command-.   I wonder how long it will take me.   (Heck,
I'm a long way from being comfortable with my skinny keyboard - still
make mistakes typing).
