TOOLS – OPTIONS – LANGUAGE SETTINGS – COMPLEX TEXT LAYOUT – CURSOR CONTROL – VISUAL/LOGICAL. It is excellent option and I'm using Visual, but editing text are not only arrows, but also Del&Bksp and it is only Logical - erase next/previous character. Please make Visual also for Del&Bksp to erase right/left character and not only logical next/previous. On Czech or English keyboard Del erase character on right and Bksp on left, on Arabic keyboard Del erase character on left and Bksp character on right, and in 2 languages documents (non-CTL and CTL) for Visual use it is confused.
I don’t know any other application that does this, do you?
Indeed, I am not sure if this is desired, but in any case, if anyone do decide to implement this, please do not mix it with the logical/visual cursor settings. I.E. logical Del & Bksp are very valid and well defined with visual cursor movement for mixed LTR and RTL sentences in both LTR and RTL paragraphs.
I know only Libreoffice to do set Cursor movement to Visual style for CTL languages, and it is really super :-), And adding this behavior also for Del&Bksp -> I'm thinking it will be really unique and really the best editor.
I advise against implementation of visual Del&Bksp.
They add a complication to the Tools > Options dialogs, yet I am not aware of any use case in which they have a clear benefit.
