Maximise and Minimise Eclipse editor window

One annoying issue i've had with Eclipse/CFeclipse is that you have to double click the editor tab to maximise/minimise the view. I have just found out that through the shortcut keys you can also do this. It might seem an obvious place to start but i'm sure i looked there ages ago. To edit the shortcut keys goto winow>preferences>general>keys and look for the command "Maximise Active View of Editor". When you get there you'll see that it uses the shortcut keys ctrl-m (for windows), this of couse is used by CFE for jumping between tags (another handy shortcut i've just learnt today). What i've done is remove the ctrl-m shortcut and replaced it with ctrl-alt-m which as far as i can see isn't used for anything.
