Hi Gwendolyn,
Re the interface differences--
One of the things to note--Windows Office underwent major design changes
between Word 2000 and Word 2002. Word 2004 borrows *some* of those design
changes, but not all, so the interface will have changed a bit from what you
are used to, but probably less than if you had gone to WinWord 2003. I'm
not sure whether this is true of the other programs.
The main shortcut key change from Win to Mac is that you use the apple key
instead of the control key. Except on the Mac, the apple key is called the
command key. So copy with cmd-C, paste with cmd-V, etc.
90% of the time switching the cmd key for the control key will do what you
are used to it doing in Office--if it doesn't, memorize cmd-Z for Undo. For
Word, there's an article on some differences between Win and Mac here:
http://word.mvps.org/Mac/Differences.html
The other thing to be aware of--Tools | Options in Office is now going to be
under Word | Preferences, or Excel | Preferences. Most of the same options
are there, just in a different place. On the Mac, in fact, the concept of
Preferences is central--all applications should have a Preferences menu
under the Application Name menu, and 90% of the little annoyances can be
fixed there, or you can set things the way you like. For the OS, you'll find
System Preferences under the Apple menu. So whenever you don't like the way
something behaves, see if there is a fix in the Preferences. This is true
across all apps and the OS.
You might also bring up Mac Help and read the "Switching from Windows"
topic, the Mac OS X section. It mentions some equivalencies and basic info,
under topics like "What's it called on my Mac?".
Hope that helps.
PS. Mac, not MAC. MAC as an all caps acronym actually has some other
meaning related to computers (Media Access Control? Something to do with
networks, I think)
