When reading and looking up new words in page view, I like to hear the pronunciation of the sentence to check my own pronunciation. Although the space bar works, it is cumbersome: one has to position, start, stop, and reposition, while repeating with an a-key is really easy. As the a-key is already active in sentence mode, it would be natural to use the same key in page mode for the same purpose. My proposal is: to activate the 'a' key to read the sentence for which a word is selected from the recording (not the computer voice). If no word is selected, ignore the a-key. Prerequisite is of course timestamps. That way, I can study both the vocab of a new word, and hear the sentence if I want to, like in sentence mode.
