Remap menu key to multitasking I'd like to remap the physical menu key of my Xperia Neo V running Cyanogenmod 9 to multi-tasking, the way it is on phones that were launched with ICS or Jelly Bean to begin with.

Apps built for ICS would then display the action overflow. With older apps, I guess an on-screen menu key would appear -- I think there is in fact an ICS phone that does this as it has only two keys, but I don't remember the name. Alternatively, the menu key would stay a menu key in these apps but this might be more difficult to achieve.

Is there any way to configure or modify Android to behave this way?
As I have just discovered, the latest Cyanogenmod 10 nightlies have this feature. Unfortunately it doesn't ever display an on-screen menu key. As a workaround, I mapped long-press of the menu key to its old function.
