'''Stop/Start''' allows you to stop time and start it again, allowing you to build without ~~it all~~ collapsing while you work.

'''Stop/Start''' allows you to stop time and start it again, allowing you to build constructions without them collapsing while you work. ''<Ctrl>+space''

'''Draw''' click and hold to draw any shape you'd like!

'''Draw''' click and hold to draw any shape you'd like! ''<Ctrl+D>''

'''~~Triangle~~''' ~~triangles (equilateral)~~ of any ~~size and initial rotation~~. Click (center ~~of base~~) drag + release (~~tip~~)

'''Circle''' circles of any radius. Click (center) drag and release (outer edge). ''<Ctrl+C>''

'''~~Polygon~~''' ~~as many sides as you would like~~. ~~Draw your own N-gon~~. ~~Click for each point, to end: right click, or left click in the circle around the original point~~

'''Triangle''' triangles (equilateral) of any size and initial rotation. Click (center of base) drag and release. ''<Ctrl+T>''

'''~~Erase~~''' ~~click on an object to erase it, or draw a line~~ of ~~destruction--erasing everything in its path!~~

'''Box''' rectangles of any dimension. Click (corner) drag + release (opposite corner). ''<Ctrl+B>''

'''~~Motor~~''' ~~click an object to pin and drive it with clockwise rotation~~. ~~It's easiest to pause the simulation, place~~ your ~~object~~, ~~add its motor~~, ~~and resume~~ the ~~simulation again~~.

'''Polygon''' as many sides as you would like. Draw your own N-gon. Click, drag and release for each point, to end return to the start point. ''<Ctrl+P>''

'''~~Box~~''' ~~rectangles of any dimension~~. ~~Click (top-left corner) drag~~ + ~~release (bottom left corner) -- like dragging a selection box in a photo editor~~

'''Grab''' drag existing objects around with the mouse. ''<Ctrl+G>''

'''~~Grab~~''' ~~drag existing objects around~~ with the ~~mouse~~

'''Motor''' click an object to pin and drive it with clockwise rotation. It is easiest to stop the simulation, place your object, add its motor, and resume the simulation again. ''<Ctrl+M>''

'''Pin''' pin a shape to the screen, it can rotate about the pin. If you want to lock a shape in place use two or more pins to stop it rotating

'''Pin''' pin a shape to the screen, it can rotate about the pin. If you want to lock a shape in place, use two or more pins to stop it rotating. ''<Ctrl+O>''

'''~~Circle~~''' ~~circles of any radius~~. Click ~~(center)~~ drag + release (~~outer edge~~)

'''Joint''' connect two objects together with a rod. Click on any object, drag to another object and release to create the joint (each end of joint allows rotation). ''<Ctrl+J>''

'''~~Joint~~''' ~~connect two objects together with a rod. Click~~ on ~~any~~ object, ~~drag~~ to ~~another object~~ + ~~release to~~ create a ~~distance joint~~

'''Erase''' click on an object to erase it, or click and hold to draw a line of destruction--erasing everything in its path! ''<Ctrl+E>''

:'''Hints''': Single clicking (no drag) with the circle, triangle and box tool will create a default sized shape. Once you have used a shape tool, it remembers the last shape you made with it, a single click will add a clone of that last shape.
