Rosemary, I'm not having a problem with citations -- the magic 'C' button works fine to place <ref>...</ref> tags.
The problem is with text which originated in tabular format, and for which i'd like to preserve line-breaks. For instance,
Name Ronald Strahle
Event Place Assembly District 4, Queens, New York City, Queens, New York, United States
Gender Male
Age 14
Marital Status Single
Race White
Relationship to Head of Household Son
Birthplace New York
Birth Year (Estimated) 1926
I'd like to be able to highlight the text...
Name Ronald Strahle
Event Place Assembly District 4, Queens, New York City, Queens, New York, United States
Gender Male
Age 14
Marital Status Single
Race White
Relationship to Head of Household Son
Birthplace New York
Birth Year (Estimated) 1926
then press the "◼︎" button (next to the magic C button above the text-entry box).
The result would be that the chosen text now has a colon (':') at the beginning of every line.
:Name Ronald Strahle
:Event Place Assembly District 4, Queens, New York City, :Queens, New York, United States
:Gender Male
:Age 14
:Marital Status Single
:Race White
:Relationship to Head of Household Son
:Birthplace New York
:Birth Year (Estimated) 1926
Kinda like the magic C button acts on highlighted text to bookend it with <ref>... </ref> tags.
