Title: Support for Control + Arrows.

PuTTY has been using Ctrl + Arrows as a toggle between normal mode and application mode thus Emacs does not recognize Ctrl-Arrows keys by default.

A workaround is to rebind the normal arrow keys (as in non application) mode to C-Up, C-Down, C-Right and C-left keys, inside Emacs. This can work things shouldn't have to come to this.

xterm.el shows what Emacs is expecting when using xterm:
