Quickparts without line breaks?

Lloyd Adams Hi Lloyd, thank you for the response.  So far I have not been able to find a solution.  Please see below:

1.  All my Quick Parts are set to "Insert content only."

2.  After reading this comment, I did some testing.  It doesn't seem to be whitespace that causes the line break, but rather punctuation marks.  I can select text with no punctuation at the end and the line break doesn't occur.  If I put a period or comma at the end of the same snippet, it creates a line break.   Even if there is no whitespace after the period, the selection area automatically expands to include two spaces after the punctuation, and presumably the line break.  It appears that Quick Parts cannot be edited, and the only way to add them seems to be to select text from an email body and hit "Save selection to Quick Part gallery."  The only solution I can see is to somehow change the selection behavior.  Is that possible?
