Hi

what do I need to put in my .emacs so that when I hit say F5 key, emacs
highlights the word at the cursor?
I will try to apply the same for the sentence with F6 and the paragraph with
F7.

thanks

You might want mark-word.

You can then extend the selection ot just delete/copy etc.

using GNU Emacs 22.3.1 (i386-mingw-nt5.1.2600) of 2008-09-07 on SOFT-MJASON
under window XP.
the command to mark-word did not make the word at point.

after googleing, I found this code which suppose to be fired M-8 to make the
word, the next fire for the sentence and the 3rd fire for the whole
paragraph. but it is not working in my system.
please try on yours and report back. thx
