OK, here's a more detailed explanation: :[range] over the selected lines, which with visual selection will appear as ',' . Those are marks set by the visual selection. g/pattern/cmd for any lines which match the given pattern, in this case \S , do the specified cmd. So, the cmd is performed for any line that has a non-whitespace character in it. Thus, empty lines and lines with just whitespace (tabs and spaces) will not match. Now, the aforementioned cmd is s/^/%/ Substitute a % at the beginning of the current line. What you asked for was to do something (comment out lines) given a condition (that the line must not be empty). So the :g/pattern/cmd allows one to do a command (s/^/%/) only when the line matched a pattern (that implied that the line was not empty). Regards, Chip Campbell

Regards, Chip Campbell It should be possible (though less obvious) to do it with only a substitute. Let's try: :','s/^.*\S.*$/# \0 i.e. prepend a hash sign and a space wherever we find start-of-line, zero or more of anything, one nonblank, zero or more of anything, end-of-line (in the range, here shown as a Visual area). Best regards, Tony.

OK, here's another possible but less obvious method, even a bit shorter: :','s/^.*\S\^/%/ This one uses a concat, and depends on having the last concat be the one used for substitution. What it means: :',' over the visually selected range s substitute the pattern that begins with something but has a non-whitespace character, AND matches the beginning-of-line with a % in the place of the last concat (ie. the beginning-of-line).

Or you could skip step one, and only add percent signs on the lines with anything in them: (select lines visually) :','s/^\(.\)/% \1 -Dmitriy On 11/15/06, A.J.Mechelynck [EMAIL PROTECTED] wrote: Meino Christian Cramer wrote: Hi, a question more driven by curiosity than by the need to change anything.

Hi Tony, yes...I know that (which is an exception... ;) I thought there would be one command to achieve the same effect instead of doing it the wrong way first and the correct it by an additional command...
