Almost, but not quite. We'll stary by hand-waving over the problem of
RGB->CMYK conversion. Now you are left with two problems.
1. Screen resolution (72 DPI) is different from the printer
resolution (> 200 DPI). IBM have a nifty trick to solve this: LCD
monitors with an enormous resolution. Sure they cost over $US10K
a throw, but you approach 200 DPI resolution. Ironically the
super-high resolution monitors are *cheaper* to make than standard
LCD monitors, but when you have a fifteen-year patent you may as
well make the most of it :)
2. The way you specify the image is different between the display and
printer. Both Windows and X suffer this problem as the programmer
has to figure out how to convert the displayed image into a
printed image. This problem is solved by adopting the same output
language for both. The NeWS and NeXT systems both adopted
"Display PostScript", which later mutated into PDF. MacOS X
adopted PDF as the display system, which allows programers to
write the display routine *once* and the output is then
same for both paper and screen.
RGB->CMYK conversion is a bit of an arse, and there is not many ways to
get around it. Ok, there is one way, you go to Pantone� and fork over a
wad of cash. You can then use Pantone� colour set which looks the same
on the screen and when printed. The GIMP will never replace Photoshop
because free software cannot afford the cost of implementing the
Pantone� colour scheme. (Caveat: I am an HCI expert, not a graphic
designer, I only dabble in most of this stuff\ldots )
Anyway, it is all by the by as everyone should get hard and learn LaTeX
:)

Global menus are things like the GNOME menu, the KDE menu, the Clip menu
in WindowMaker, the root menu in TWM...

Try using the Cut and Paste menu options for doing this. Cut and Paste
work from a slightly different clipboard (called CLIPBOARD) than the
middle mouse-button clipboard (which uses PRIMARY). The only trick is
that you have to be using GTK+ >= 1.2, QT >=3, XEmacs >= 20, and
Netscape/Mozilla >=4, as these systems have all agreed on how Cut and
Paste should work.
