Does anybody know a keystroke to open the upper left context menu in Windows operating systems? I'm referring to the one listling:

  • Restore
  • Move
  • Size
  • Minimize
  • Maximize

  • Close

In particular I want to restart individual 'inactive' putty sessions without using the mouse by any chance.

  • Similar problem using putty for an employer via citrix: mouse clicks don't reach the actual application, so I get a generic context menu rather than putty's menu. I can't find any way to access settings. Anyone know a trick?

You need to set System menu appears on ALT-Space or System menu appears on ALT alone in PuTTY's Windows | Behaviour settings.

  • Blast. I'd just gotten there. :-) Jun 7, 2010 at 12:32
  • That's what I looked for. Cheers!

  • This is the first program I've ever wanted to access this menu for and the shortcut was disabled by default... Why?... I was so confused that I was looking up how to do it in general because I thought I had the key combo wrong when it didn't work. Does alt+space do something special on a terminal too? I think it should be enabled by default.

Just adding to the answer from Mike Fitzpatrick

In order for the changes to be effective, you need to:
Open the context menu (upper left) > Click Change Settings... > Windows (Left Pane) > Behaviour
Tick one of the items "System menu appears on.."
and click "Apply"
