Hello and thank for info. NVDA uses screen scraping, it hooks Windows
API like ExtTextOut, TextOut, etc. This rarely works well, and it is
used as a last chance when everything else fails.
Also there is an OCR, but it is only for static things, i.e. take a
snapshot of window and OCR it. So for example an inaccessible installer
can be used quite well, but something as dynamic as edit text area
cannot, at least now.

To rebuild the IDE, open the Tools Menu.
2nd last entry: "Build Lazarus ... profile name"
Or last entry "Configure build lazarus" which opens a dialog, so you can
specify compiler options.
How does NVDA read the content of a control? Does it do OCR?
Because SynEdit is entirely custom drawn. SynEdit does not expose it's
text through any API.
If it is OCR, maybe it helps to switch SynEdit to black and white.
(Tools: Options, then Editor, Colors / But you have to switch of each
color by itself.
Also make sure you go to the config for "Markup and Matches" and disable
everything there. (Especially the new option "Outline (global)"
If it is an issue with scrolling: Try compiling with the option
-dSynNewScrollBarUpdate

Hello,
One of your suggested changes indeed showed a system caret, but there
is probably another change, because the NVDA is unable to show me
lines after I scrool with a down arrow to try to read the contents.
But that may be a NVDA problem.
For now I will use external editor for editing and special IDE
features like code completion directly in the environment.
I now have another question, a bit unrelated to this thread but
relevant for me. If I make a change like this, I obviously need to
rebuild the IDE. Currently I am using the command
lazbuild --build-ide= -q -q
Can someone perhaps suggest a better command, another parameters for
example? I am not sure if that is totally correct. I will then save
the command to b.bat to make rebuilds easier.
