match of escaped parentheses

match of escaped parentheses

[Alexander Heide]

I want to use parentheses matching in a document, that contains 
expressions like "\(" and "\[". Emacs seems to recognize these 
expressions as escaped parentheses. But that's the behavior I don't 
want. Emacs should also match these expressions with ")" and "]", i.e. 
ignore the backslash characters.

In which major mode?

PS: Set the syntax of the \ char to something else than / or \.

Well, the behavior in latex-mode is pretty lame. (For \{ and \} as
well as the aforementioned forms.)  This is unfortunate, because
these "escaped paretheses" symbols are used a lot in latex, and one
would often like to find where e.g. a set begins by using paren
matching.

Thank you. The major mode was 'fundamental-mode'. And indeed the 
character table shows (C-h s):

\		\ 	which means: escape

I switched to 'text-mode' (M-x text-mode) where parentheses are matched 
as I want it.

I tried to edit a Mathematica notebook. It was opened in 
'fundamental-mode'. I changed to 'text-mode', where '\' does not mean 
'escape'.
