The grave-accent key selects the last staff item selected, even if you have a system item selected. This isn't quite the same as tabbing off a system item onto the next staff item but you can use it to go back to the last staff item that you were on without having to go back to the top and work through the score again. There are three situations in which this keystroke comes in useful. 1. You press escape to clear a selection. You'll need to do this if you want to play a MIDI keyboard without over-writing the score. Once you've finished "doodling" you can press grave-accent to reselect the item you were on before you pressed escape. 2. You select a staff item and then add a system item, such as a key signature or tempo mark. After you've added the item it will be selected. Pressing grave-accent will take you back to the staff item that you had selected before adding the system item. 3. You are arrowing through the score and hear that a system item is at or near the current item. You then use the system items dialog (Alt+F2) to select that item. Pressing grave-accent will then take you back to the staff item which you had selected before opening the system items dialog. In the current RC1, you should always press the F5 key after selecting the system item, to give the script time to "fix" the location, before using the grave accent key. This should be fixed in the next release. - [dgc] Regarding the tab key, I made a conscious decision not to override it, since it is a fundamental keystroke provided by Sibelius itself and it's a keystroke that you may need to use to get out of trouble if the scripts lock up. The grave-accent key is there as a way of working around situations in which the tab key throws you back to the start. I have been considering a keystroke which will take you to the next staff item after a system item, on whichever staff was last being edited but I'll need to give some thought as to how it ties in with the rest of the interface. I've already added some new keystrokes which select the next or previous system item, meaning that you won't have to use the system items dialog, but I'm fast running out of keystrokes. This means that I really have to think carefully now as to whether a feature is worth the loss of another keystroke.
