Can this be done?
mm.
No it is not possible as it stands, but it would but the ability to toggle individual filters from the bar, and assigning a keyboard shortcut to the toggle, would a very useful.
In your case you can already toggle 'Read Aloud' via CTRL+R in Windows or CMD+R on Mac to save a few mouse clicks.
Ok, thanks.
Type "Read Aloud" in the "Go" box and drag the "Start Reading Aloud" command to the Toolbar?
