How to test it with the word list file opened? I try to put > the above code on the minibuffer of the opened word list file's frame, > and then hit `M-:', but it doesn't work. I put that in some buffer (say *scratch* -- but loading the file from disk works too), execute the definition by putting point at the end and doing C-x C-e. Then the function is defined. After that, I go to the buffer I want to test for the longest line, do M-x eval-expression (goto-longest-line) to call the function. Point ends up (so one hopes :) at the buffer's longest line. As I said, there are bugs in there, so beware :-) Cheers - t --LwW0XdcUbUexiWVK Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAmEToFkACgkQBcgs9XrR2ka/yQCeKi7ExgmOYeDohr6jEOX2J0eB cVsAn0I2XCSARB+qZKdu0Zsi9QBk5LQe =sKxr -----END PGP SIGNATURE----- --LwW0XdcUbUexiWVK--
