Did you re-bind hotkeys? To which keys?

[pickpacket]

I'm -- finally -- trying to learn the hotkeys for different actions in the game. I find them really cumbersome, however. Typically I keep my right hand on the mouse and would use my left hand for hotkeys. But I find that it's not much a shortcut to move my hand to 9 (build railway station when the train toolbar is active), or manage a combination like Fn+Sft+F7 (show the train toolbar).

Have you re-bound your hotkeys to something less cumbersome? Which keys did you choose? Feel free to share your hotkeys.cfg
