I've learned that this program only allows a single space after a period, so by using the HTML for the first space, then the space bar for the second, a standard double space is accomplished.  Like here.  And here. 

Then a single line spacing can be accomplished with the "enter" key, as I did above to begin this sentence on a new line.



This was a double "enter" key command.

This was a single "enter" key command.  And the HTML for italics and bold and underline were used here.  (However, they must be typed-in manually, so if you don't know the HTML code you'll have to make do with using CAPITALS to add emphasis.)

I hope this as saved you some time as you make your entries.
