I'm using View Navigation Walk and the jump functionality is strange. I press spacebar but instead of jumping I go flying to whatever surface is straight ahead of me. It's more like a "hookshot" or "grapple gun" maneuver than a jump. Actually, I think this is the Teleport feature. But if that's the case, what key is "jump" mapped to?

When I search for "jump" in the Keymap section of Preferences nothing relevant turns up.
