Creating a Blank Line

WordPress does not allow a blank line to be created in Visual mode.  There are basically two methods to work around this problem:

1)  Switch to HTML mode and place the code <br> wherever you would like an extra blank line.  If you are switching back and forth between Visual and HTML modes, this method may not produce the desired results as WordPress strips out extra blank lines. Several <br><br><br> can be added on the same line to create additional spaces.

2) Enter a space in Visual mode and then highlight the space and make it a header.  Of course, since it is a space, nothing will show up except a blank line.
