Is there a quick way to navigate through a large level?

I have been working my way through the Lerpz tutorial on Unity3D 3.5. I am now at the part where I am supposed to add lasers to the tunnel at the very far end of the map. I want to check if I positioned the laser correctly. But to do that, I would have to start the game, run to the tunnels and see the lasers in action. This is very time consuming as the starting point for the player is several hundred meters and there are several tricky jumps that I need to go through just to get across the platforms between the gardens and the tunnels.

Is there a faster way to preview specific portions of a level during development? Or am I stuck with having to playtest through the level just to preview how things are at the very far end of the level?

For level navigation, I make a bunch of cubes w/o colliders with descriptive labels like “farm”, “doomhill,” … so I can double-click to jump there. To keep the scene not too cluttered, can child them all to either AAnavigate or ZZnavigate (to put it at the front or back of the list.)

To move the player to a game object, child it, set position x/y/z to 0’s – use the TAB key after each 0 – then unchild.

Or, if you move to the same areas a lot, just make “cheat keys”:

if(Input.GetKeyDown("1")) player.position = new Vector3(280,1,364);`
... same for 2,3...
