@ldubost Under "New document" on the cryptpad.fr home page, I choose "Document". Once the editor loads, my focus lands in an unlabelled multiline editable area.
When I type in this area and try to read what I've written, NVDA (my screen reader) reports absolutely nothing. Essentially, the editor is always determined to be blank.
If I try to use the standard Tab and Shift+Tab keystrokes to move focus around the page, nothing happens. My focus is trapped inside the editor.
If I press Escape to use my screen reader's own cursor (called "browse mode"), I find:
1. An alert, "This pad is not in your CryptDrive.", at the bottom of the page. It has no accessible markup (like dialog) to indicate that it's a notification I can dismiss, and because focus didn't land in it, I had no idea it was here. I dismiss it with the "DON'T STORE" button, at which point keyboard focus is lost.
2. I now find another alert, "We need your help!", which likewise is not accessibly marked up. I dismiss this too, with "NOT NOW", and focus is lost again.
3. Now that these notifications have been dealt with, I manually return to the editor by pressing Tab a lot. NVDA still reports it as blank, and doesn't see any of the text that I type or paste.
4. Returning to the browse mode cursor, I look around the page and fine, among other things: 66 buttons with no accessible label, a menu bar ("File"/"Home"/etc.) with no accessible markup, menus in that bar that I don't seem able to open, unlabelled text fields for setting font attributes with no labels, disabled text inputs with no labels, and so on.
5. Trying to go back to the home page, I find that all keystrokes for moving to my browser's address bar (Alt+D, Control+K and Control+L) are prevented from working by the application. I have no choice but to close the tab instead.
Much of this is irrelevant because if I can't read the document I'm working on, the rest of the interface doesn't matter. And this level of inaccessibility isn't limited to this document type; for example when I create a new sheet instead, I find nothing resembling an interactive grid or table.
