You're right, Gil. I couldn't spot any mention of that on the site. A review at dadsgamingaddiction site says:
The controls are not rebindable, but are fairly simple for the game’s purposes. The WASD keys move the player around, left shift runs, left control crouches, the “F” and “L” keys activate your flashlight and lantern, respectively, “I” opens your inventory, “J” opens your journal, and “Space Bar” jumps.
Additionally: "At present, the game automatically saves your progress [only] when you complete an important objective or unlock the next area."
So manual saving doesn't seem to be possible.
