This is a widely used system and was operational at one time in Denemo
- I think it could be re-instated, though quite why it was discontinued
I don't recall. But as any command within a menu can have its own
keyboard shortcut it isn't needed to get access to the commands (the
desired shortcuts do need to be created, which may be difficult for the

yes, that's the default in Denemo (well, Ctrl-s for save and Ctrl-S for
"Save As") but where I was thinking the problem could arise is that a
dialog then pops up to enable you to choose where to save and that is a
graphical dialog. But, from what you are saying, blind people can cope
with pop-up dialogs?

The documentation doesn't, unfortunately, contain a list of the default
keyboard shortcuts, because they are available from the Shortcuts
command in the Help menu. Attached is the result of clicking on that
command on my program - the shortcuts are not the default ones, because
I have customised them for my own use of Denemo.

The crucial step needed would be to design the set of shortcuts that a
particular blind user would want.  I say "particular" because music
typesetting encompasses an enormous range of possibilities - there are 
over 1,300 commands available in Denemo - only some of which are of
interest to any one particular user.
