In many of my topics, I use a horizontal line (select
Insert; Horizontal Line) to separate links at the bottom of
the topic from the rest of the text. RHv5 inserts a line that is
50% of the width of the topic, so I double-click on the line and
change it to 100%.
Is there a way that I can set the default width of new lines,
so I don't have to insert and then edit each one?
