Here is an idea I think would be useful. In Engrave mode, when making changes to a Master Page set, it would be handy to be able to type “F”, “S”, and “N” to toggle the switches for “Frames”, “Staff Spacing”, and “Note Spacing”. I find a lot of mousing around is necessary to turn the switch on, do the edit, turn a different switch on, make the edit, etc. Perhaps while in this mode other shortcuts could trigger actions such as “Insert Music Frame”, “Insert Text Frame”, “Insert Graphics Frame”, etc.
Obviously, this is a low priority in the scope of things, but the beauty of this forum is that we have a place for people to make suggestions and be heard out by not only the users but crucially, the development team. “GO TEAM”!
