would be very fine to have a way to comment out several rows of code
(something like /* and */)
sometimes, while debugging, I found the necessity to
comment out several procedures at once,
and it's very disturbing to have to comment every single line.
I used my favourite editor (Ultraedit) most the time and if offers this as a configurable option with buttons for it. Then the whole block get a ';' at the linebegin.
