# Crosshair

The last tool in the xScope bag of tricks is the Crosshair. This is a simple tool that helps you locate and align points on screen. Just click on this toolbar icon shown above to activate the Crosshair.

The Crosshair that appears looks like this:

1. The guides (horizontal and vertical)
2. The position

By default, the Crosshair tool reports positions relative to the upper left-hand corner of the screen. You can, however, set any point as the origin—this allows you to get positions that are relative to an arbitrary point on the screen.

A good example of this is getting a point within the bounds of the ruler. If you have the Rulers tool displayed, you can select the "Center Follows Ruler" option from the Crosshair menu. After enabling this option, the position of the crosshair will always be relative to the point where the rulers are joined.

Alternatively, you can use ⌘0 (Command-Zero) to set the Crosshair origin using the current mouse position. After the new origin is set, the tool will display the offset from that position.

By default, the crosshair will appear no matter which application you are using. In some cases, this can be distracting; you can set a preference to hide the crosshair when xScope is in the background.

Finally, you'll find that the Crosshair tool is most effective when used in conjunction with the other tools. In addition to using it with the Rulers (as described above), try turning on the Loupe to get a close up of the current position. The Guides and Frames tools can also benefit from a crosshair—allowing quick position measurements without creating a new guide or frame.
