@defun skip-chars-forward character-set &optional limit
This function moves point in the current buffer forward, skipping over a
given set of characters. It examines the character following point,
---------- Buffer: foo ----------
@end group

+Note that char classes are not currently supported in
+@var{character-set}; they will be treated as literals. Thus you
+cannot use @code{"[:alpha:]"} instead of @code{"a-zA-Z"} to include
+non-ASCII letters. A way to skip forward over all letters is:

+@example
+(re-search-forward "\\=[[:alpha:]]*" nil t)
