 PuTTY users have reported that the F2, F3, and F4 shortcut keys are not working properly.  PuTTY sends the same escape sequences as the linux console for F1-F4 by default.  You can fix this problem in the PuTTY config, Terminal -> Keyboard -> Function keys: Xterm R6.  See: \fIhttp://www.mail-archive.com/screen-users@gnu.org/msg01525.html\fP
