C Mode Motion Commands
----------------------

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

`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.  When going backwards,
     `#elif' is treated like `#else' followed by `#if'.  When going
     forwards, `#elif' is ignored.

`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.

     If point is within a string or comment, or next to a comment (only
     whitespace between them), this command moves by sentences instead
     of statements.

     When called from a program, this function takes three optional
     arguments: the numeric prefix argument, a buffer position limit
     (don't move back before that place), and a flag that controls
     whether to do sentence motion when inside of a comment.

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

`M-x c-backward-into-nomenclature'
     Move point backward to beginning of a C++ nomenclature section or
     word.  With prefix argument N, move N times.  If N is negative,
     move forward.  C++ nomenclature means a symbol name in the style
     of NamingSymbolsWithMixedCaseAndNoUnderlines; each capital letter
     begins a section or word.

     In the GNU project, we recommend using underscores to separate
     words within an identifier in C or C++, rather than using case
     distinctions.

`M-x c-forward-into-nomenclature'
     Move point forward to end of a C++ nomenclature section or word.
     With prefix argument N, move N times.
