Once I notice a rather bad habit (such as using left shift for : - uncomfortable on a dvorak kinesis), I simply bound the combination to an exclamation mark so I'd notice every time I did it. That's a really good idea! I might bind some bad-habit key combos to system beep because I hate the system beep.
