uninstall/Reinstall

[Adlerhorst]

how do you uninstall if game resides at Steam?or can I do it off the DVD?
I feel I have to execute a reinstall in order to reset controls back to original default -- unless there is a simpler way.
I have lost the bubble on changes I made to Warthog and now there are a lot of bindings that do not work and I can't track back. It would have been simpler if I could have printed out the original control bindings as a worksheet but I couldn't figure that out
