You can set InDesign shortcuts to whatever you want they are fully customizable. My advise would be to unlearn quark shortcuts all together and start using the defaults in InDesign. The advantage of this is that Adobe uses similar shortcuts throughout CS so in Photoshop, Illustrator, InDesign and so on you will be using the same keystrokes.

2.0 & CS can open Quark 4 files - funny thing is I sometimes have more issues converting Quark 4/5 files to Quark 6 then converting Quark to InDesign. (honestlly I think this problem is created more by trying to use collected fonts from OS9 in OSX)

All of Adobe CS is Mac OSX only. I mean come on the only reason you would be using OS9 still is if your employer forces you to!!

My only problem with InDesign is the reluctant Quark-heads - the kind of people who blame InDesign for their mistakes.

Question to service provider - "Why did my font change I sent you the fonts didn't you load them??"
Answer - "Ohh that's because the file was in InDesign"

This along with a lot of other BS such as "Ohh we have to charge you more $$ because you used InDesign instead of Quark" I could go on and on forever about this, but just let me sum it all up by saying I love InDesign it has made my job so much easier, and my shope fully supports it, I can output any InDesign file you send me Mac or PC without any issues. In the rare case where there is an issue - InDesign can Export as a PDF, Illustrator, or TIFF file.
