Manually scroll while Read Aloud is active

[Rohan2217]

I want to manually scroll calibre myself while read aloud is active. Currently, the Read Aloud feature auto scrolls/ turns to the next page when the active sentence/word goes beyond the bottom of the screen. I want the auto scroll feature to work as usual, but I also want to scroll manually while it is working. Is there anything I can do in preferences or make changes to viewer.js to make it happen? Any help would be appreciated.
