Thank you! I "know and love" TextWrangler, having used it ever since the 
demise of the
free version of BBedit, and having used that since about 1998.

On a Mac that's great; but, with the exception of some very 'focussed' 
work, I do all my stuff
on Linux, and, as yet, am unaware of a Linux equivalent to TextWrangler.
