Hi Daniel,
Already there, in two different ways! If you press Cntl-Tab, you move one screen to the right. Cntl-Shift-Tab takes you one screen to the left.
Additionally, there are keyboard shortcuts to take you directly to a specific screen, as identified by the underline on the tab name. Use the Alt key and the character to go to the desired screen For example, Alt-H takes you to the Header screen, Alt-A for Details, Alt-B for Bill to/Ship To, and Alt-T for Totals.
We've tried to design Adagio so that you never have to use the mouse, though of course in a Windows application, the necessary keyboard shortcuts aren't always obvious. Let us know here if you have other suggestions - that's one way to make a product better!
We're glad that the Adagio experience has so far been a good one!
Regards,
