Hi,

To check for properly paired { and } I'd like to do an incremental 
search for both { and }, "{ | }", i.e. '{' or '}'.

^s { followed by | } terminates the search with "Keyboard macro 
terminated by a command ringing the bell".  This is not what I want.

Q: How do I do that search (incrementally) ?

Very good question! I'd try with M-C-s or isearch-forward-regexp. For example like that:

	ESC C-s [ { | } ] RET

This would regular expression (almost) incrementally search for characters in the set ('[' ? ']') of characters '{' or '|' or '}'. You can search for the next character from this set with C-s (or C-r backwards). To re-search you can invoke ESC C-s C-s (or C-r).

Correction! You want to find any { or } and some text in between, right? Then it would be:

	ESC C-s { . * }

and would high-light "{what ever}". This is a simplistic approach which would find {some command argument \othercommand{its argument} maybe some more}". Backward it would be "{its argument} maybe some more}"!
