31.11.1 C Mode Motion Commands

This section describes commands for moving point, in C mode and related modes.

M-x c-beginning-of-defun
M-x c-end-of-defun

Move point to the beginning or end of the current function or top-level definition. These are found by searching for the least enclosing braces. (By contrast, beginning-of-defun and end-of-defun search for braces in column zero.) If you are editing code where the opening brace of a function isn't placed in column zero, you may wish to bind C-M-a and C-M-e to these commands. See section Moving by Defuns.

C-c C-u

Move point back to the containing preprocessor conditional, leaving the mark behind. A prefix argument acts as a repeat count. With a negative argument, move point forward to the end of the containing preprocessor conditional.

#elif’ is equivalent to ‘#else’ followed by ‘#if’, so the function will stop at a ‘#elif’ when going backward, but not when going forward.

C-c C-p

Move point back over a preprocessor conditional, leaving the mark behind. A prefix argument acts as a repeat count. With a negative argument, move forward.

C-c C-n

Move point forward across a preprocessor conditional, leaving the mark behind. A prefix argument acts as a repeat count. With a negative argument, move backward.

M-a

Move point to the beginning of the innermost C statement (c-beginning-of-statement). If point is already at the beginning of a statement, move to the beginning of the preceding statement. With prefix argument n, move back n - 1 statements.

In comments or in strings which span more than one line, this command moves by sentences instead of statements.

M-e

Move point to the end of the innermost C statement or sentence; like M-a except that it moves in the other direction (c-end-of-statement).
