CrossHair displays two full-screen lines intersecting your mouse cursor when you press a hot key. As you move the mouse cursor, the lines follow over any program or window. The program is tiny, and runs completely transparently until you call up the crosshairs. It's useful for eyeballing any kind of chart or tabular data on screen, and for aligning objects in graphics or design applications.
The setup program will automatically enable CrossHair. At any time, press one of the the activation hotkeys to make the crosshairs appear. There are two activation hotkeys:
Roving hotkey: press to make the crosshairs follow your mouse as you move it around. The default roving hotkey is Control+Backtick, as shown at the left.
Stationary hotkey: press to make the crosshairs remain fixed at your mouse cursor's current location. The default stationary hotkey is Control+1. (The 1 key is adjacent to Backtick on most keyboards.)
You don't hold the activation hotkey down. Instead, press it again to make the crosshairs disappear. You can always move and click the mouse while the crosshairs are displayed, in either mode.
