Nothing to install. Enter the hall
Look around and walk
On a computer, click the floor to walk there. Drag to look around, and use the wheel to zoom. The arrow keys also move you. On a touch screen, tap the floor to walk, drag with one finger, and pinch with two fingers.
Greeting, bowing, and beads
Gassho puts your hands together. Bow continues until Stop, which stands you up. If no cushion is free, look around and press again. On the bead screen, hold a bead and move it up or down. 108 beads make one round.
Sound and rooms
Ambience, chant, and effects are separate. Switching Cheongyeon rooms opens the same hall in another seat. A room number is not a level.
The introduction is on the Sansa online temple.
