pre_form: Feature to pre-fill form parameters when opening a specific site. It is convenient for sites that you visit often, but it may introduce some security issues. Be careful when using this feature, especially `submit' params described below. Default configuration file for pre_form is ~/.w3m/pre_form. The syntax of entries in the configuration file is as follows: url <url>|/<re-url>/ form [<name>] <action> text <name> <value> file <name> <value> password <name> <value> checkbox <name> <value> [<checked>] radio <name> <value> section <name> <value> submit [<name> [<value>]] image [<name> [<value>]] textarea <name> <value> : /textarea If <action> is set, a form which has matched <action> attributes will be configured by this pre_form. A line beginning with text, file, passwd, select, textarea means that it will set value to <value> in input, select or textarea element which name attribute matches with <name>. A line beginning with checkbox, radio means that it will check input element which name and value attribute matches with <name> and <value> respectively. If <checked> is 0, no, or off, the checkbox will be unchecked. A line beginning with submit or image means that it will submit input element whose name attribute matches with <name> (and value attribute matches with <value>), or submit on the last <input type=submit> element if no <name> was specified. You quote \, ' (single-quote) or " (double quote) as you do in shell.
