",`, and '
Three different types of quotes are used in Maple for three different purposes: as string delimiters; as symbol delimiters; and as a means of delaying evaluation of an expression.
The double quote symbol (") is used as the string delimiter.
The left single quote symbol (`) is used to form a symbol.
A pair of right single quotes (' ') is used to delay evaluation of the enclosed expression --- see uneval
In earlier versions of Maple, the double quote symbol was used as the ditto operator. This facility is now provided by the percent symbol (%).
