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"
