sound file to be used by PuTTY alone, or even by a particular

\H{config-window} The Window panel
The \q{Lines of scrollback} box lets you configure how many lines of
text PuTTY keeps. The \q{Display scrollbar} options allow you to
hide the scrollbar (although you can still view the scrollback using
-Shift-PgUp and Shift-PgDn). You can separately configure whether the

If you are viewing part of the scrollback when the server sends more
text to PuTTY, the screen will revert to showing the current
If you want a different window title, this is where to set it.

+As well as the \e{window} title, there is also an
\c{xterm} sequence to modify the title of the window's \e{icon}.
This makes sense in a windowing system where the window becomes an

+\cfg{winhelp-topic}{connection.tcpkeepalive}

+\e{NOTE:} TCP keepalives should not be confused with the
+application-level keepalives described in \k{config-keepalive}. If in
+doubt, you probably want application-level keepalives; TCP keepalives
+are provided for completeness.
+
+The idea of TCP keepalives is similar to application-level keepalives,
+and the same caveats apply. The main differences are:
+
+\b TCP keepalives are available on \e{all} connection types, including
+Raw and Rlogin.
+
+\b The interval between TCP keepalives is usually much longer,
+typically two hours; this is set by the operating system, and cannot
+be configured within PuTTY.
+
+\b If the operating system does not receive a response to a keepalive,
+it may send out more in quick succession and if terminate the connection
+if no response is received.
+
+TCP keepalives may be more useful for ensuring that half-open connections
+are terminated than for keeping a connection alive.
+
+TCP keepalives are disabled by default.
