Is there a keyboard shortcut for enabling dictation on iPad?
Solution 1:
I would also love to have this.
However, as of right now there is no keyboard shortcut to directly start dictation on the iPad.
Currently, the most convenient way, as you said, is to press and hold the downward facing arrow on the bottom right until the virtual keyboard pops up and then press on the dictation button.
Solution 2:
Apple added new shortcut in the recently release. Just press ctrl twice.
