Hotkey combinations for all units

[Jazcash]

I think all units should be accessible via a series of hotkeys. For example, you could have E open the economy tab, then if M is pressed next it will select a Mex, just like Starcraft does.

I realise that there are already a lot of hotkeys in-use, so this may not be applicable. However, I think if you enforced unit hotkey mode then it would make a lot possible. E.g. Once E is pressed, the next letter key you press would be interpreted as the economy unit you want, and not anything else.

Just an idea.

I think this isn't feasible, there are almost 200 units in each faction and only 4 spare (alphnumeric) keys, but the new hotkeys widget has a few more units under 'C' than before. And it has functionality to implement this easily, if needed in future.
