CGI scripts run under HTTP and as such you cannot interact with them as you do with a standard script.
You could send a Javascript function to the client (web browser) that detected a key press and made a new request (HTTPRequestObject) to a separate script which returned the second part of your page, this response could then be set as the innerHTML of a div on the already loaded page.

bbmessage.cgi
BBMESSAGE.CGI(8) System Manager's Manual BBMESSAGE.CGI(8)
NAME
bbmessage.cgi - CGI utility used for proxying Xymon data over HTTP
SYNOPSIS
bbmessage.cgi
DESCRIPTION
bbmessage.cgi(8) is the server-side utility receiving Xymon messages sent by the bb(1) utility over an HTTP transport. The bb utility nor-
mally sends data over a dedicated TCP protocol, but it may use HTTP to go through proxies or through restrictive firewalls. In that case,
the webserver must have this CGI utility installed, which takes care of receiving the message via HTTP, and forwards it to a local Xymon
server through the normal Xymon transport.
The CGI expects to be invoked from an HTTP "POST" request, with the POST-data being the status-message. bbmessage.cgi simply collects all
of the POST data, and send it off as a message to the Xymon daemon running on IP 127.0.0.1. This destination IP currently cannot be
changed.
The CGI will return any output provided by the Xymon daemon back to the requestor as the response to the HTTP POST, so this allows for all
normal Xymon commands to work.
SECURITY
bbmesage.cgi will only send data to a Xymon server through the loopback interface, i.e. IP-address 127.0.0.1.
Access to the CGI should be restricted through webserver access controls, since the CGI provides no authentication at all to validate
incoming messages.
If possible, consider using the bbproxy(8) utility instead for native proxying of Xymon data between networks.
