Grave accent (`) - cursor is specified by using a ClearWin+ parameter from windows.ins.
cursor_name is a standard character string (can be replaced by @) used to
identify a cursor via a resource script.
The alternative uses a grave accent modifier together with const which is
Standard arrow cursor
Text I-beam cursor

A square with a smaller square inside its lower-right corner
Double-pointed cursor with arrows pointing Northwest and Southeast

Another pair of alternatives uses a positive integer N to provide a
selection of N different cursors. In this case the variable sel is
given a value in the range 1 .. N in order to specify a particular
cursor. It is not necessary to call window_update@ when sel is changed.
The examples below illustrate the first pair of alternatives.
cursor_name can also take the form of an
integer handle surrounded by curly brackets or the name of an
external file surrounded by curly brackets.
