There are a number of commands in Emacs which apply to "words." Examples include
transpose-words, etc. The definition of "word" seems to vary a bit between the commands. For example,
forward-word will stop at an underscore within a word (e.g.
mark-word does not stop at the underscore.
Is it possible to change the definition of "word" when I am in a prog mode so that Emacs will use the appropriate word boundaries for the syntax of the current language?
When I am in
c-mode I want
forward-word to skip over underscores, and when I am in
lisp-mode I want
forward-word to skip over both hyphens and underscores, etc.
