The special command sequences available are described in the "Using PuTTY" documentation page.

However, to check the tunnels you have open, you would right-click the PuTTY icon in the upper-left corner of the window and choose "Change Settings", then drill down to Connection → SSH → Tunnels. From here you and view and modify the tunnels you're using.

With Putty, if you want to send an escape char (like ^[ with telnet), just press CTRL and $. Also, it may depends of your keyboard layout, as explain of the following link Putty escape chars (Read the comments for more per-keyboard solutions).
