+* Ctrl and arrow keys doesn't work in putty! What do I do?
+
+putty inverts the sense of the cursor key mode on ctrl, which is a bit hard for
+tmux to detect properly. To get ctrl keys right, change the terminfo settings
+so kUP5 (Ctrl-Up etc) are the adjusted versions, and disable smkx/rmkx so tmux
+doesn't change the mode. For example with this line in .tmux.conf (assuming you
+have TERM set to xterm):
+
+set -g terminal-overrides "xterm*:kLFT5=\eOD:kRIT5=\eOC:kUP5=\eOA:kDN5=\eOB:smkx@:rmkx@"
