I've taken code from default.js to create a message menu but there are
two components, that I don't understand that are in the code:
What are node_action: value? NODE_XFER was just copied from the file
menu definition. 
What is the "eval: 'bbs.messages_cmds++' used for?  

const message_menu = {
        file: "messages",
        eval: 'bbs.message_cmds++',
        node_action: NODE_XFER,
        prompt: "\x01-\x01c\xfe \x01b\x01h" + gettext("Messages") + " \x01n\x01c\xfe \x01h" + time_code +
                " \x01n\x01c[\x01h@GN@\x01n\x01c] @GRP@\x01\\ [\x01h@SN@\x01n\x01c] @SUB@: \x01n",
        num_input: shell.get_sub_num,
        slash_num_input: shell.get_grp_num,
        command: {
         '&': { exec: 'msgscancfg.js' },
         'F': { eval: 'bbs.scan_subs(SCAN_FIND)'
                        ,msg: '\r\n\x01c\x01h' + gettext("Find Text in Messages") + '\r\n' },
         'J': { eval: 'shell.select_msg_area()' },
         'L': { eval: 'bbs.list_msgs()' },
         'M': { eval: 'bbs.scan_subs(SCAN_NEW, /* all */true)' },
         'P': { eval: 'bbs.post_msg()' },
         '/P': { exec: 'postpoll.js' },
         'R': { eval: 'bbs.scan_msgs()' },
         'S': { eval: 'bbs.scan_subs(SCAN_TOYOU)'
                        ,msg: '\r\n\x01c\x01h' + gettext("Scan for Messages Posted to You") + '\r\n' },
         'U': { eval: 'bbs.scan_subs(SCAN_TOYOU, /* all */true)' },
         'V': { exec: 'scanpolls.js' },
        '/V': { exec: 'scanpolls.js', args: ['all'] },
        },
        nav: {
        '\r': { },
         'Q': { eval: 'menu = main_menu' },
         '>': { eval: 'shell.sub_up()' },
         '}': { eval: 'shell.sub_up()' },
         ')': { eval: 'shell.sub_up()' },
         '+': { eval: 'shell.sub_up()' },
         '=': { eval: 'shell.sub_up()' },
         '<': { eval: 'shell.sub_down()' },
         '{': { eval: 'shell.sub_down()' },
         '(': { eval: 'shell.sub_down()' },
         '-': { eval: 'shell.sub_down()' },
         ']': { eval: 'shell.grp_up()' },
         '[': { eval: 'shell.grp_down()' },
        },
};
