Using (Ctrl + r, m) key combination is giving me a message "The key combination (ctrl+r, ctrl+m) is
bound to command (JustCode_ExtractMethod) which is not currently available" - same
goes with JustCode_IntroduceVariable (ctrl+r, ctrl+v).
Methods however are in fact available - its just the shortcuts that are broken. Under ctrl+` 'extract method' option is available and it's working just fine.
