It was nice to see such a prompt response to the request for marker accessibility from the menu bar. One of the most annoying aspects of Mellel for me (or perhaps the only really annoying aspect) is the fact that the "Go to Page..." navigation button is not accessible from a menu and cannot therefore have a keyboard shortcut assigned to it. If it was such a seemingly simple matter to add menu accessibility to the markers, why hasn't the same been done for this navigation button? I'm sure I can't be the only person who would really like to see this fixed.
This is a nice addition. But I'd still like to see an option to automatically set the marker so that one could simply go through the document and select text, which would automatically be marked.
As I recall, this is the way the marker works in MS Word, although I very rarely even open that application any more.
