Lynx will display local files written in the HyperText Markup Language (HTML), if the file's name ends with the characters .html, .htm, .shtml, .htmlx, .html3, or .ht3. HTML is a file format that allows users to create a file that contains (among other things) hypertext links to other files. Several files linked together may be described as a hypertext document. If the filename does not have one of the suffixes mapped by Lynx to HTML, the -force_html command line option can be included to force treatment of the file as hypertext.

When Lynx displays an HTML file, it shows links as "bold face" text, except for one link, which is shown as "highlighted" text. Whether "boldface" or "highlighted" text shows up as reverse video, boldface type, or a color change, etc. depends on the display device being used (and the way in which that device has been configured). Lynx has no control over the exact presentation of links.

The one link displayed as "highlighted" text is the currently "selected" link. Lynx will display the file associated with the selected link when a right-arrow or a Return key is pressed. To select a particular link, press the up-arrow or down-arrow keys until the desired link becomes "highlighted," and then press the right-arrow or Return key to view the linked information. Information included in the HTML file tells Lynx where to find the linked file and what kind of server will provide it (i.e., HTTP, Gopher, etc.).

Lynx renders HTML files and saves the rendition (and the source, if so configured in the lynx.cfg file) for initial display and should you select the link again. If you do select a link again and have reason to desire a new fetch and rendering of the file, use the NOCACHE command, normally mapped to 'x' and 'X', instead of the right-arrow or Return key when positioned on the link. You also can force a new fetch and rendering of the currently displayed document via the RELOAD command, normally mapped to Control-R.

When a binary file is encountered Lynx will ask the user if he/she wishes to download the file or cancel. If the user selects 'D' for download, Lynx will transfer the file into a temporary location and present the user with a list of options. The only default option is Save to disk, which is disabled if Lynx is running in anonymous mode. Additional download methods may be defined in the lynx.cfg file. Programs like kermit, zmodem and FTP are some possible options.
