At least on macOS it's possible select text and press Option-Escape to read the selected text loud. Something similar should be possible on other operating systems.
Thanks, strangely it does not work for me (I use Mac as well). There is no notification or sound when I press Option and Escape. Do you know the reason why?
Check System Settings → Accessibility → Spoken Content → "Speak selection" to see if the feature is enabled, and click (i) to check the shortcut key assigned.
its a plugin! im going down some of my google top searches to provide the link. Enjoy !
