Each player has a direction arrow that can be changed by clicking on
it while holding shift.
If it's not visible you can check the box 'direction arrow' in halo menu.
When you tell a player to move forward it will move in the direction
of the arrow.

This is not currently used in Etoys.

For Kedama.

A simple character recognizer that let you draw characters or gestures
in a text field.
CTRL + r in for example a Workspace. Then you can draw with the mouse.
I'm not sure how it works. I do not think it is used at all...
