ToME: the Tales of Maj'Eyal

After updating to 1.1.5, I noticed that the escape key no longer functions in the game.
On the key bindings menu (accessible from the main menu), there is an option called "Exit menu". The current binding for this is wheeldown. It's possible that it was changed by accident by me. Someone in the chat channel told me that his Exit menu is bound to esc, which is presumably the default.
If this Exit menu binding is the reason the escape key no longer works, then I would just have to change it back to escape to proceed. But the flaw here is that pressing the escape key while trying to change a key bind cancels the change, making it impossible to bind the escape key to any function.
I also couldn't find any option to restore key bindings to defaults.

Any suggestions, besides reinstalling the game? It's possible that I'm overlooking something very simple.

In the user folder for Tome (not the game folder, it'll be something like documents and settings/username/t-engine/4.0 on windows) there's a file called keybinds2.cfg.

Open this, and it lists the changes made to the keybinds. Delete the line relevant to the menu attached to your mousewheel, and it SHOULD revert to it's default setting.

This is based on understanding, not actual tests, so make a copy of the file first please.

Thank you. I couldn't find a relevant file because I was searching in the TOME folder, not the T-Engine folder, which I have in separate paths.

I deleted keybinds2.cfg and default key bindings were restored.
