Hello.
The manual says:
If you place the cursor at the beginning or just behind the end
of the displayed text and press <BACKSPACE>, you will remove the
(invisible) bracket at that location.
The problem for me it that it depends on the way I arrive at those
locations. For example, for '[[xx]]', seen as 'xx' underlined, if I
have the cursor on the right of it and have it go towards the left
just after the second 'x' and press <BACKSPACE>, then the behavior is
as I expect (I see '[[xx]'), but, if I have the cursor on the left and
have it go to towards the right just after the second 'x' and press
<BACKSPACE>, then I see a single underlined 'x' (after a second
<BACKSPACE> I see '[[]]').
Is this normal? (tested with emacs -Q with master, with emacs 24.5.1
and 26.1)
Incidentally, is there a way to have things like [[xx]] behave as
plain text? (I am not talking about literal links which are still
understood as links.) I have tried 'quote', 'verse', 'verbatim',
'comment', 'example', and org code block: none work.
In the case of 'example' the 'xx' string is not underlined, yet
hitting <RET> on it generates "org-link-search: No match for fuzzy
expression: xx".
In the case of an org code block the 'xx' remains underlined but <RET>
on it generates "Evaluate this org code block on your system? (yes or
no)", which is strange to me...
PS: for me this is not a theoretical issue: In many circumstances I
would like '[[xx]]' instances not behave as links. I would be happy
if I could change the link format (e.g., use {{xx}} instead -- is it
possible? (I fear it is not.)
Thank you.
Regards

Yes, it is normal Emacs behaviour. See (info "(elisp) Invisible Text").
I guess we could clarify the manual. Suggestions welcome.

Yes, there is. Insert a zero width space after the opening brackets.

=[[xx]]= and ~[[xx]]= are not links; try to export them.
However, `org-open-at-point' still treats them as such -- see last
paragraph in its docstring -- because this was a desirable feature for
some users, IIRC.

No, you cannot change link syntax, but you don't need to, either.

OK, thanks a lot.

I guess you could simply add a footnote after "location." in the
excerpt above.
- Minimalist: See (info "(elisp) Invisible Text").
- Hardly more: For more details, see (info "(elisp) Invisible Text").
- Facetious: If unexpected behavior occurs, check (info "(elisp)
Invisible Text").
- Too kind: Beware, the precise behavior depends on how the cursor has
been placed there -- see (info "(elisp) Invisible Text").

Thanks again. I would also advocate some mention of this in the
manual (if not already there somewhere, which I did not find). I was
thinking about an extra sentence at the end of "4.1 Link format";
something like:
To have ‘[[text]]’ constructs behave as plain text and not as
links, insert a zero-width space (C-x 8 <RET> ZERO WIDTH SPACE
<RET>) between the opening (or the closing) brackets.
However, I still don't see how this can be something convenient for
massive and frequent use. In my case, I often yank and work on code
fragments written in the Mathematica language, for which the [[]]
syntax is used for list indexing. Well, I guess I'll have to learn to
live with that...

Indeed. Thanks once more.
