This section describes commands for moving point, in C mode and related modes.
C-M-a ¶C-M-eMove point to the beginning or end of the current function or
top-level definition. In languages with enclosing scopes (such as
C++’s classes) the current function is the immediate one,
possibly inside a scope. Otherwise it is the one defined by the least
enclosing braces. (By contrast, beginning-of-defun and
end-of-defun search for braces in column zero.) See 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).
