We have been on NAV 2009 RTC for over 18 months. The biggest challenge we have had with keyboard shortcuts is the lost productivity the users experience now that most shortcuts take an extra key stroke (because all the Classic menu buttons are now buried in the RTC "Related Information" button; and because the Classic "functions" button is not buried under "Actions ... Functions"; or F-key replaced with Ctrl+?). This sounds like a petty complaint. But it is the main driver as to why most of our users prefer classic to RTC. They are just faster with Classic. Here are a couple examples: Warehouse Clerk looking up bin contents from item card/list: Classic: Alt+i+b RTC: Alt+i+i+b A/P Clerk applying freight charges from purchase order line: Classic: Alt+l+a (item charge assignment); alt+u+r (get receipt lines); choose your lines; alt+u+i (suggest assignment) RTC: Alt+a+u+r (get receipt lines); choose your lines; alt+a+u+i I often see the comment that "old users prefer Classic, so don't show it to new users ... just start them out on RTC". Users who know both prefer Classic. So why not introduce new users to Classic? They can be more productive if they use classic. Of our 70 users, 5 prefer RTC. those are the users that have a very specific repeated task where the role center neatly summarizes their daily work (this is fantastic for them). But, any user that has a broad array of tasks that may need to do research in multiple parts of the system, or whose tasks require multiple windows/pages to complete, prefers Classic becasue the keyboard shortcuts aren't as keyboard intensive.
