wjt is a slider widget for the X Window System that allows the user to select values within a range using the keyboard or mouse. It presents a bar at the top or bottom of the display with a slider area including legend labels, and optionally, a prompt on the left. When the user adjusts the slider position, its value is printed to stdout. wjt grabs keyboard and mouse input while running. wjt was inspired by, and its code is based on, dmenu.
