LYNX-DEV Re: numbered form inputs and popup options

[Laura Eaves]

Update to previous mail:
I jsut added keypad_mode=LINKS_AND_FORM_FIELDS_ARE_NUMBERED
to the O)ptions menu and used this instead of LINKS_ARE_NUMBERED
to activate the numbered form fields.

Updated README is below.  New zip/diff/README at http://www.intac.com/~leaves/
New diff is a little larger, but not bad.

> 1) Link numbers are added for all form input fields

> 3) For popup menus, a link number is generated for the option list,
>    and then for each option, an option number is generated in parentheses.
