I have remapped my controls but the tutorial screen still displays the default control for "Cancel". Can I still complete the tutorial?

Yes.

Almost every control displayed on-screen in the tutorial automatically updates if you remap your controls. However, the control for "Cancel" will always display as the Escape (Esc) key.

When you are prompted to use the "Cancel" command, just press the key to which you have mapped it.

NOTE: To check or edit your control configuration, select Main Menu → Options → Interface → Edit Keyboard Bindings.
