Allowing a person to go through and edit how some text is read aloud, for example equations. Instead of being read literally, letting a person select or highlight the equation and enter in what it means in natural language.

Example: A{p(t), q(t)} is currently read as "A p t q t" when, in the context of the book, it should be "Some function, A, of the momenta and spatial phase space coordinates".

I don't see a way something very context-dependent could be programmed in, so having a way for the reader to manually change how the equation is interpreted and read might work better.

On Windows 10 Enterprise 1909 build 18363.2094,
Adobe Acrobat DC version 2021.011.20039,
opening file Colour Cycle.pdf
Top menu
File > Print...
Print Dialog
Top section (Printer, Properties, Advanced, Copies, Help)
Checkbox "Print in grayscale (black and white)" is unchecked.
Expected behaviour: prints in colour
Actual behaviour: printed in black & white.

Why?

Workaround:

File > Print...
Print Dialog
Top section (Printer, Properties, Advanced, Copies, Help)
Properties
Tab 1 (Paper/Output)
Right hand side
Output Color: Black and White
Dropdown list
Select "Color"
Click OK
Click Print
Prints in colour.

For comparison, Microsoft PowerPoint
Open Colour cycle.pptx
File > Print
Left hand column,
Print button, Printer section, Settings section
Below Settings section
Print All Slides, Full Page Slides, Collated, Color
Select Color
Prints in colour.

Let's check if its consistent.

Left hand column,
Print button, Printer section, Settings section
Printer section
Printer Properties
Paper/Output tab
Output Color
Dropdown "Black and White"
but
PowerPoint
File > Print...
Left hand column
Settings section
still says "Color"

Both Adobe Reader DC and Microsoft PowerPoint are inconsistent with hidden system settings that decide whether a document prints in colour or black & white.

This problem took 3 embedded software engineers about 20 minutes, and 3 attempts, to solve. This was done during working hours, at a cost to the company. Please can we have a user interface where the Colour/Black & White setting is consistent with how we would expect it? (that the Print... dialogs show the same selection as the printer properties).

Thank you for making Adobe Reader for helping us read our Controlled Docs, attach files to our documentation, and communicate effectively across teams!

This issue happens with keyboard-only and screen reader users.

When exporting, saving or publishing a document as a PDF, the interactive features within that document (such as hyperlinks) don't work when the PDF is viewed in a browser (any browser). The only way an interactive PDF works as intended is when it is opened with Acrobat Reader.

There must be an issue between the interactivity within a PDF and how browsers render that PDF document for accessibility. Can this be fixed so it doesn't matter whether a user has Acrobat or uses a browser to view a PDF and interact with it?

Many times, I am confronted with a text string that needs a search (I generally use Google) and from within Acrobat I must select and copy the text, then go to the browser and search. I know it sounds fundamentally lazy...but these steps if repeated over and over take time. From the Chrome browser, we can select and then right-click text and "Search in Google" is an option. Acrobat is a much richer environment for working with the PDF but then the constant charade (for instance in a legal document with citations) of select, copy, open the browser, open or find a tab to work in, paste might be unnecessary.

Any chance that Adobe Reader will be integrated with Microsoft Edge Chromium in a similar way Adobe Reader is integrated with Internet Explorer 11 via ActiveX? Users opening pdf in IE are not even aware they see Adobe with plenty of features. ActiveX is legacy technology and not supported by modern browsers but maybe Adobe plans some deeper integration with Microsoft? I'm working in corporate environment with 70 housand users and received feedback that Microsoft Edge built-in pdf reader cannot open many pdf-s created in Adobe products.So in Edge browser there is option to redirect PDF to Adobe reader by downloading pdf and opening it. This leads to additional step and extremely bad user experience of clicking pdf in one application that after few seconds is opened in another application. Users want's the 'Old way of IE'.I've been pointed by Microsoft that this capability it's a question to Adobe not Microsoft.

Clicking on internal links in pdfs make you jump to the pointed position: E.g. in scientific papers, if you click on the source number you jump the source which is normally at the end of the pdf.

If you want to continue reading it is (as far as I know) impossible to jump back. It would be nice to include some options inspired by browsers: I would like to have the option to open the same pdf in a new tab/window again at the desired position so that after checking the source you can continue reading in the original tab. Also buttons to jump back/foward would solve this problem.
