Within Adobe Reader X, specifically in a PDF documetn, and highlighting/selecting text using SHIFT+ARROWS or SHIFT+CTRL+ARROWS, there is no visual highlight occurring. When performing text selection ,it is really important that visual highlight also occurs, allowing for blind to highlight specific text to show to sighted.

Browse mode exists primarily because there is no caret (or no reliable caret) in these browsers. It is extremely difficult to synchronise between individual characters in our browse mode representation and the underlying document. I'm not even sure Reader allows for programmatic selection of text, though a quick look at the API suggests it might.

@jcsteh You expressed thoughts on this ticket in #2183 (comment) more than five years ago. Any updates? CC @Qchristensen and @feerrenrut also in case their sight may aid in diagnosing this somewhat visual-oriented issue...

Ideally, if we could visually highlight text while selecting, it would, as noted, aid sighted / low vision users, though how easy it would be to implement and how much overhead it would bring could be the issue. In some cases - in both Adobe Reader DC and web browsers for instance, you can select text with the mouse and it is visually highlighted, even though it may not be when done with the keyboard. I'll let others comment on the feasibility of implementing it though.

Ah highlighting the word being spoken is, I believe, a different issue to the one this ticket is for, which is that when reading a PDF file (although the same is true in some, but not all other Browse mode documents), when you select text, for instance with shift+right arrow, the text is not visually highlighted.

For highlighting what is being read, the best option at present is the "focus highlight addon": https://addons.nvda-project.org/addons/focusHighlight.en.html

@Qchristensen is the text visually selected when switching to focus mode while reading the document in Adobe Reader and selecting with shift+arrow keys or ctrl+shift+arrow keys?
If yes, then this issue migh be obsolete but there is anoter one. When switching to focus mode, NVDA does not report the characters at all when pressing arrow keys.

Selecting text in browse mode selects the text (so you can copy it, for instance) but does not visually highlight it.

Switching to focus mode, selecting text (with shift+arrows or control+shift+arrows) does a very interesting thing: It selects text, and highlights it visually, but NOT the text that NVDA was on. (Sometimes it is above, sometimes it is below, I haven't worked out exactly why it moves where it does). NVDA does not read anything when navigating or selecting in focus mode.

I have Adobe Reader DC, version 39.012.20040.17853.
