For years I have been using a different prefix key for nested instances on tmux. I use \
on my own server, but a
for any other servers I connect to and start a nested tmux session.
I have found this trick which uses Shift+Arrow Keys to switch between windows and nested instances, which is much better.
However, it does not work when I am using PuTTY (using Windows) but it does when I use KiTTY. I cannot figure out why it is not working with PuTTY.
Ctrl+v, Arrow Keys returns the same codes in the terminal when using either programs.
EDIT:
Just after starting a bounty I have realized that Ctrl+v, SHIFT+Arrow Keys does actually come up with different codes.
PuTTY:
SHIFT+Left Arrow = ^[OD
SHIFT+Right Arrow = ^[OC
SHIFT+Up Arrow = ^[OA
SHIFT+Down Arrow = ^[OB
KiTTY:
SHIFT+Right Arrow = ^[[1;2D
SHIFT+Right Arrow = ^[[1;2C
SHIFT+Up Arrow = ^[[1;2A
SHIFT+Down Arrow = ^[[1;2B
So how do I change PuTTY so that it sends the same codes with SHIFT+Arrow Keys?

The answer is you can't, since this is a bug in PuTTY. This was discussed some time ago at stack - https://stackoverflow.com/questions/6202310/putty-shift-arrows
I had the similar problem with tmux and PuTTY, and I switched to KiTTY.
