Delete the standard carriage return and replace with Shift-Enter between
each of the several lines in question. This will bring them together and
eliminate the paragraph spacing between them.
Thank you. What I wanted to get was a paragraph, not a set
of lines separated by hard carriage returns. What I would like
to do is to select several contiguous lines, press a keyboard
shortcut, and obtain a paragraph rather than several lines.
