There should be a command to save your keybind settings, as in /save_keybinds or something along those lines.
What you would have to do is setup your keys in-game, and use this command to save it to a custom file. You can then set this to be used in the config file I explained above. I know I'm not being very precise, but I don't have time to thoroughly explain the process I use at the moment!
*EDIT*
Here, this may help more:
