Facilitate the navigation into a score

Hi,

I asked a question in the French forum about the facilities that MuseScore provides to navigate into a document, it seems that there are not a lot.

Also I found not easy to navigate like I would like into a document.

PDF Reader or Microsoft Word are examples of soft that provide more facilities. They could by learned to enhance the navigation into MuseScore.

This is some main defaults that I found:

• As the different pages are listed horizontally, even if all the line of the score is visible, I need to navigate first vertically in to the page and then horizontally between the pages.
  It is not difficult but it complicates a quick read of the document.
  An option would be to propose a vertical list of all the pages of the document.
  A soft like Microsoft Word, to facilitate a bit more have an option to hide the top and the bottom margin. It is like if I read an infinite paper roll.
  This is different of the continuous view that is already provided because the layout is fully respected.
• The [Page down] and [Page up] button move the same way in the document, it is not depending of the zoom.
  In software like Microsoft Word and PDF reader, it is possible to only use the [Page down] button to read all the document. The part of the document that is displayed is just the following of the part that was visible before the use of the key. The first goes from the start to the end of the document, the second in the opposite direction.

The current behaviour of MuseScore is also available in a soft like PDF reader with the following combination of keys: [Ctrl]+[Page down] and [Ctrl]+[Page down].
MuseScore could also implement these shortcut to navigate.

• When no item is selected, the arrow keys are off. They could also be used to navigate in the document.
  Combination could be used to enhance more. For example one could be used to go to the side of the page (left, right, top or bottom according the key). Another could be used to display the part that is just not visible (the one on the left, right, top or bottom according the key). It is way to enhance the [Page down] and [Page up] I proposed above.
• It is possible to start the navigation into the document just by pressing the key and moving the mouse to navigate but I regularly make mistake when the mouse is too near of a movable item as instead of starting the navigation, I move the item. There is nothing to identify the zones of the document that can be used to start the move, they are between score lines, but not everywhere because of items that exceed of the line.

The middle button could be used for this with no risk of mistake. To facilitate the scroll, a key could be used to force a horizontal or vertical move. In this case, it is only the orientation that is used, when the mouse goes right, the move is horizontal to the right, even if the move is not really horizontal.

Even if most of the enhancements proposed here are for the page view some of them would also interesting for the continuous view.

Bertrand.
