Please note that the information I found in Vista/Office 2007 about macros is almost certainly a reflection of the incompetent documentation about features of both Vista and Office 2007.
At first exploring them, I found multiple instances of "you can't do that." In several places, I found statements that you can't modify toolbars, BUT in Word 2007 there still is a place to "Customize" Word, and it appears to allow you to create new toolbars, and to add and remove icons from them.
Help file info stated quite specifically that macros are not permitted; but there is a place in Word 2007 where you can record a macro by recording keystrokes, and there is a macro edit button. There also are separate file formats for "Word 2007 documents" (.docx) and for "Word 2007 documents with macros" (.docm). There are separate formats for document templates, .dotx and .dotm, depending on whether macros are included in them. These would not exist if the statement that "you can't use macros" was really true.
My interpretation of what I've found is that OFFICE 2007 CAN DO ANYTHING ANY PREVIOUS OFFICE VERSION COULD DO, but Microsoft has assumed all users are idiots and shouldn't be told how to do anything "complicated." They've thus buried the useful information "so the poor idiots won't get hurt."
I expect to find that Office 2007 is pretty good. The DOCUMENTATION for users in Office 2007 is an insult to me, and to most here, and reflects incompetent assumptions by Microsoft about who will use the programs and what they need to do with it.
NO SENIOR MANAGER who was directly associated with Vista remains at Microsoft. There is hope for eventual sanity, - - - maybe.(?)
