7. Expression register "= *quote_=* *quote=* *@=*
This is not really a register that stores text, but is a way to use an
expression in commands which use a register. The expression register is
-read-only; you cannot put text into it. After the '=', the cursor moves to
-the command-line, where you can enter any expression (see |expression|). All
-normal command-line editing commands are available, including a special
-history for expressions. When you end the command-line by typing <CR>, Vim

-the expression. If you do not enter an expression, Vim uses the previous
+read-write.
