Putty shortcut and tricks

I'm switching between many systems and lastly work quite a lot with putty. My ssh session sometimes timeouts and putty 'hangs'. I can always reconnect by using mouse:

• navigate to upper left cornet and press the putty icone
• from the menu select Restart session

Problem

What keyboard short can be used to restart putty session.

Solution

In the default settings for putty enable the keyboard shortcut for ALT + Space.
Now if you want  to reconnect your session you can press:

Shortcut : ALT+Space followed by 'r'
