Selections non selectable modifiers

Some modifiers, such as articulations, aren't selectable. The keys h, i, j, and k bring up articulations that aren't selectable, but are placed on the note automatically. You can toggle position and on/off by repeating the key.

Additional articulations are available from the of articulation button group.

You can customize the articulations selected by the key bindings by changing the ui/keyBindings/editorKeys.ts file, or by providing your own bindings. See the custom-keybinding.html example in the project.
