Unfortunately, debugging is broken in the current release of 7H and was fixed literally the day after once we became aware of it. Since it was such a small change, we decided to wait to incorporate it into the next release. But that has nothing to do with your issue anyway.
The default keys are currently the 1998 controls which are the numpad buttons. Enter is OK, + is Menu, 2, 4, 6, 8 are your movement keys, etc. If you want to change from the defaults to another preset, like Steam, or if you want to import your own controls directly from the game, go to 7H>Settings>Game Launcher>Controls.
