Thanks for your interest in this project. Do you have ideas on how this
system you mention might work? The main thing thst is not currently
keybaord-acciessible now are the palettes. One idea lasconic had was to
make these searchable much liek the Symbols dialog (press "Z" to display)
or the Instrument list (press "I") is, or for that matter the shortcut
definition dialog in Edit / Preferences / Shortcuts. So you could type the
first couple of letters of the name of the palette item you want and the
palettes would be filtered to show only elements whose names start those
letter, and then you could navigate the resulting list with up/down keys
and hit Enter to apply. This much would probably actually be pretty easy
to add. But I think we need more than this - I think we need the ability
to create regular user-assignable shortcuts as well, so if there are
certain symbols you use a lot, you can apply them more directly. I could
imagine each palette cell having an optional "shortcut" property that let
you assign shortcuts to any element you wanted. Probably in reality there
would be a single underlying command "apply palette element" that the
shortcut system would use to apply the selected palette element, something
like that.
There is also existing experimental code from another GSoC student who
worked on this two years ago to make the palettes traversable by keyboard,
and when I tested this code, it did seem to work pretty well. it is not
merged yet so you'd need to get his branch and build it, we can discuss
this here or on IRC.
Another problem to tackle is score navigation. The student I mentioned
above implemented a lot and that was merged and is in 2.0.2 already, but we
still don't have a way to select anything but notes, key and time
signatures, clefs, and barlines. That is, you can't use the keybaord to
navigate to a text element or an articulation or a crescendo marking. We
need a new command that will navigate through these.
Braille output would be ncie, but simply exporting to MusicXML then
converting using FreeDots is already possible to do by hand. I think a
more interesting integration with MuseScore might be to output the current
selection to a Braille output device (physical devices with raised pins you
can touch that respond in real time) so that as you navigate the score, the
Braille device tells you want you are looking at. This would be more
efficient for many users than what we currently do, which is output a text
decription to the status ine for a screenreader to read.
There are a few other user interface issues to sort out - shortcuts to move
the focus from one window to the next (eg, from score to toolbar to
inspector to selection filter).
Realistically, doing all of this in one summer is probably not feasiable,
but these are ideas to cnsider. i think keybaord control for palettes is
especially high priority though, as it will also benefit sighted users
(especially if we allow the assigning of shortcuts).
