I think the silvery theme was carefully chosen to almost match one of the standard Windows ones. We can't cover each and every theme. It's better to aim for being consistent within the documentation. Also the silvery one is clearer for accessibility purposes. I don't know the name, i think it is called "Galaxy" in Ubuntu.
The Ubuntu theme is called XP Silver. Galaxy is the icon set.
Some of the pix in the book are taken from Windows XP or Windows 7, or
from different themes in Ubuntu. Changing them all to be consistent is
low on the priority list (see lots of previous correspondence on this
topic). Besides, having them all consistent doesn't mean they will
look like what the user sees. We just have to live with the fact that
no matter what we do, LO won't look exactly the same on everyone's
systems.
See also comments interspersed in Hazel's note below.
I am using the Galaxy theme (which is
what we used for OOo.org documentation)under Linux. If I
should be using a different theme, please tell me.
You're fine. See above for my comments on Galaxy and themes.
If the dialogs really do look different in Windows, maybe a
note should be included at the beginning of the book -
possibly where the list of Mac keys is.
Yes, unfortunately it's probably necessary to keep reminding people
that things look different on different systems. We do already mention
in several places (including in Chapter 2) that some *fields* appear
only on Windows, or only on Mac, or only on Linux, and we mention the
LO Open/Save dialogs being different. But we haven't been reminding
people that the general appearance may differ from what they see.
We also mention in several places that the "expansion symbol" is a
triangle on some o/s and a + on others.
