I don't think there is a list over all console commands.
You can change to window mode (Alt+Enter) and bring down the console (Shift+Esc) to free the mouse. I believe this was possible from 0.7.6 and later.
Thanks! This is exactly what I've been looking for. Last (but not least) question: Is there a list of all standard maps in v0.8.1? I just need all their names, without any special information ...
