        That's trivial to implement.  You simply need to have ^V
return the character mapped to F_LINK_NUM in form_getstr():

[...]
    /*
     *  And go for it!
     */
    for (;;) {
again:
        ch = LYgetch();
#ifdef VMS
        if (HadVMSInterrupt) {
            HadVMSInterrupt = FALSE;
            ch = 7;
        }
#endif /* VMS */
        if (ch == 22) {
            ch = '0';
            break;
        }
[...]


though it might be better to get a bit fancier, by adding an LYE_foo
command for ^V in LYEditmap.c, and go into the loop for a function
that actually checks and returns the character mapped to F_LINK_NUM,
in case it was changed from '0' in lynx.cfg.
