Please, where can I find documentation about the
keywords utilised in files like ~/.kde/share/config/konquerorrc
Please do somebody has some link to documentation about this ?

An example of such a keyword was (for me some years ago)
PopupsWithinTabs=false
which I changed to
PopupsWithinTabs=true
for my convenience

This file is not documented as such because the entries in it could be generated by other KDE components (the file viewing component is not part of Konqueror itself).

The only documentation is the source code of Konqueror and the loaded components themselves.

Thank You bcooksley for this help
I regret this, because so it is very difficult for me, to
