Specific Key or Button to Exit Tour Tool

[slugore]

On many, many occasions I have accidentally exited the tour tool by pressing the wrong key after a full bake. On most models this isn't an issue but sometimes a long bake can make it very painful to do this. Is there any way that I can make it so that I only exit tour tool by pressing just one specific button so that my sausage fingers don't accidentally hit "e" instead of "w" and exit the burn?
