putty-config.txt

Terminal -> Bell -> Action to happen when a bell occurs = None (bell disabled)
Window -> Lines of Scrollback = 1000 (For the quick "Oops, what did I do" moment)
Window -> Reset scrollback on keypress = check
Window -> Reset scrollback on display activity = uncheck
SSH -> Remote command = tmux a -t base || tmux new -s base (if you're going to use this connection for tmux)
SSH -> Protocol = 2 only
SSH -> Auth -> Attempt authentication using Pageant = check (Most Important One)
SSH -> Auth -> Private key file for authentication = c:\full\path\to\rsa.ppk
SSH -> X11 -> Enable X11 forwarding = check (Important if you use X11 applications that need to display to your laptop.)

(copy/paste with mouse in putty should be done holding shift key)
