Acessibility option: Mouse-only zoom
Please consider adding an option to assign a different modifier key to mouse zoom, other than Ctrl, including the ability to set it to none (so that the mouse wheel zooms without any key pressed). Most modern software have that option, including Inkscape, Gimp, Krita...
Navigation is one of the most frequent actions while using MuseScore, it should be possible to do it with the mouse only, as well as entirely with keyboard. Moving around is possible with a mouse (both left click and middle click have the same function, perhaps redundantly), but zooming is not and requires the use of the other arm.
Adding this option would significantly benefit people who have impaired movement in one or both hands and have difficulties use the keyboard and the mouse at the same time. It would also be very useful to people who are just used to a different workflow and use Alt, or Shift to zoom, like in some proprietary software.
