[Lazarus] Lazarus code editor: what happened with the caret?

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.

Thanks
