Alternatively, if the number is given a -'p' suffix (e.g., 123p), Lynx will make the page -corresponding to that number the currently displayed page, and the first -link on that page, if any, the current link.

If the user has set Keypad mode to Numbers act as arrows, then only '0', rather than every number, will be treated as an F_LINK_NUM command for invoking the Follow link (or goto link or page) number: prompt. The '0' will not be treated as the first digit for the number, or number plus suffix, entry. +

Numbers are associated with form fields only when Links and form +fields are numbered mode has been selected. If you have selected +Numbers act as arrows or Links are numbered mode, you +can seek form fields in the document via WHEREIS searches for strings in +their displayed values. If they are INPUT or TEXTAREA fields with no +values as yet, you can use two or more underscores as the search string, +because underscores are used as placeholders for form fields in the +displayed document. + +

When you have invoked a popup window for a list of +OPTIONs in a form's SELECT block, each OPTION is associated with a number, +and that number will be displayed in Links and form fields are +numbered mode. In any keypad mode, the F_LINK_NUM +('0') command will invoke a Select option (or page) +number: prompt, and you can enter a number, and optionally a +'g' or 'p' suffix, to select or seek an OPTION in that +list. If only an number is entered at the prompt, the corresponding OPTION +will be selected and the popup will be retracted. If the 'g' +suffix is included, then you will be positioned on the corresponding OPTION +in the list, paging through the list if necessary, but it will not be +treated as selected unless you enter the ACTIVATE (RETURN or right-arrow) +command when positioned on the OPTION. For purposes of paging (e.g., in +conjunction with the 'p' suffix), a page is defined as +the number of OPTIONs displayed within the vertical dimension of the popup +window. +
