Why don't you just say the name of the field you want to fill

You can change focus by saying the name of the text box. In this demo, you can say either "percentage" or "color". You can also change focus the old fashioned way, with your mouse. Speech focus is indicated by the yellow highlight. Once focus is set, you can then say the content of the field (either a number or a color). If you dont know what is valid input, say "options".

Say submit to submit the form.
