I just discovered that if you go to the settings section in the right lower corner of the Chromebook, at the bottom click on advanced, in the accessibility section click on manage manage accessibility features, under keyboard and text input,turn on enable dictation, speak-to-type. Then you can put the cursor in the actual box here on the Forum and dictate directly into rather than copy and paste.
It does not seem quite as smooth, and you have to keep your voice going or else the microphone turns off rather quickly compared to the copy and paste method in the Google Document blank form.
I think it will take a little bit of practice to get a bit better doing it this way rather than the copy and paste method, but I think with a little bit of time,it is trainable.
