+Start \*(We and make COMMAND the last (rightmost) column displayed.

+Then use the up/down arrow keys to position the display so that some
+truncated command lines are shown ('+' in last position).
+You may have to resize your xterm to produce truncation.

+Lastly, use the 'j' \*(CT to make the COMMAND column right justified.
