xshell 5 keep alive option missing [3]

Hi,
Where is the keep-alive option in xshell 5?
in xshell 4 ->Properties ->Connection

has a keep-alive option, i don't see that in xshell 5. i love xshell 5 but can't use it unless i get the keep-alive option.

Please help with a work around. I am using ssh and cannot modify the sshd_config file that's on the server.

Program Ver. : Xshell 5

Please see the attached image.

how to send a "Enter" string ?

Could you make this happen?

eg; support such "{enter}" , or "CRLF"


Thanks!

'\n' will work as Enter.
