As a workaround add and/or modify these lines in(to) your config file:
keyCommandLeft[]={};
keyCommandRight[]={};
keyCommandForward[]={};
keyCommandBack[]={};
keyCommandFast[]={};
keyCommandSlow[]={};
Normally this wouldn't be a huge problem, since I am used to edit config files by hand, but since all keyboard keys are indexed by numbers you actually have to lookup each key if you want to edit the config file.
