Navigating by sentence
I am wondering how to navigate by sentence in NVDA? The shortcuts for that are listed as Alt+Up arrow, Alt+Down arrow for moving to the previous and next sentences and Alt+Numpad 5 for speaking the current sentence. However, none of these shortcuts seem to do anything for me. Is there some configuration change needed to make it working? Do these shortcuts work for anyone?
I'm using NVDA 2017.4 and the latest Windows 10.
