Quick implementation of flash.geom.Point in Loomscript. I took loom2d.math.Point and used it as a base, and added all the methods from the Flash version, as well as a distanceSquared method since thats on loom.graphics.Point.
package loom2d.math
{
/**
* A slightly less simple Point class.
*/
public struct Point
{
public var x:Number, y:Number;

Emacs shortcuts

Emacs Control Keys

Control

Commands using control will always look of the form C-? where ? is some key that you're to press while holding control.

Meta

Commands using meta will always look of the form M-? where ? is some key that you're to press while holding the meta key (most often this is the alt key in modern terminals). Pressing ESC will also activate the meta key.
