In some circumstances you can drag and drop teleporter pyramids into otherwise inaccessible locations (sometimes you need a grate or window, etc, but in can go through smaller gaps or some doors).
In general,
drop a teleporter pyramid on the ground, left click drag the teleporter, right click to 'cancel', move the cursor where you want the pyramid to go and release the left mouse button. This should toss the pyramid through walls, etc; not sure if the normal distance range applies (I only tried this after I saw it mentioned in a forum post).
