Rotate%2090%C2%B0%20CCW.jstalk

// Rotate 90° CCW (cmd shift 7)
// v.02
// This is a recreation of a standard Fireworks command and shortcut, allowing you to rotate an object or selection 90 degrees counter-clockwise. To avoid blurry edges and strokes, a ‘snap to pixel’ option is included and is enabled by default.
// Note that if you prefer to rotate each object in a selection individually, you may hold the Option key when running the command. However, the Option key modifier will not work with the command's assigned keyboard shortcut.

// USER VARIABLES
// Rotation around an object's centerpoint may result in "off-pixel" alignment, causing blurred edges or strokes. To correct for this, set "snapToPixel" to true. Note that if multiple rotations are applied, some ‘pixel migration’ or object repositioning may occur.

var snapToPixel = true; 	// To disable snap to pixel, set to false.
var rotateEach = false;		// To rotate objects individually, set to true.
