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?
