Programmers sometimes need an existing string or file-contents as a literal
String (String constant) in their program code.
The trouble with simply copy-pasting such a string is that all existing single quote
characters have to be doubled. Otherwise, it will not be a legal string literal.
The editor's popup menu offers two functions to do this for you:
To insert a file, select
"More" - "More" - "Insert File as String Literal"
and choose a filename.
To insert a string which is already in the copy-paste buffer,
select:
"More" - "More" - "Paste as String Literal"
