Expression Movement

Some major modes provide functions to move backwards and forwards over expressions written in a buffer in the programming language that the mode supports (see section Mode-Specific Expressions), for example the Lisp mode defines the syntax of Lisp forms written in a buffer.

Function: forward-exp &optional count

This function moves the cursor over count expressions, as defined in the current buffer. If the buffer has no expression definitions an error is signalled.

Function: backward-exp &optional count

Moves backwards over count (or one) expressions, leaving the cursor at the beginning of the expression. If the buffer has no expression definition functions an error is signalled.
