A toggle steps a mode on rather than setting it: toggle_text goes verbose, terse, off, verbose; toggle_sound turns sound off or on, except on a scatter plot, where sound that is on is combined or separate and goes combined, separate, off, combined. So check `modes` from maidr_list_commands first, run a toggle only as often as reaching what the user asked for takes, and check the `modes` each run returns. Commands that open a dialog or text field are the reader's to use and cannot be run. If the reader has a MAIDR dialog open, nothing runs. Otherwise, if they are not inside the chart, the command waits and runs when they next enter it: tell them so, and do not claim it has happened -- unless you pass focus: true, which moves their keyboard focus into the chart, where the command runs half a second after they hear where they are.
