[TxMt] check unmatched parenthesis

[salvo]

Hola,

is it possible to add to the menubar a command to check if there are  
unmatched parenthesis, brackets, brases and so on for all languages?

I saw in Wiki the request to add a functionality like emacs  
parenthesis hilighting: it is a useful think, 'cause not always we  
write a new page, and then autocompletion is very nice, but sometimes  
we correct an old page, and often there are unmatched parenthesis to  
check.

Many thanks

Salvo
