How to mark new text in a buffer ?

How to mark new text in a buffer ?

[Xavier Maillard]

Hi,

I am looking for the best way to identify new entered text into a
buffer and show that information.

For example, I am visiting a file-based buffer -i.e. a buffer
visiting a file. It has already content and I am typing something
like "foo bar". I want to display "foo bar" in such a way that we
get direct information on what is new and what is old.

Any idea ?

In addition to what has already been mentioned (`highlight-changes-mode' and
`diff-buffer-with-file'), and depending on what you need, you also have `M-o o'
and the other `M-o' keys (use `C-u'). These are also available from menu Edit >
Text Properties > Face (without `C-u'). But be aware that this does not work
with font-lock-mode. See `(emacs)Format Faces'.
