Event keys

During case data acquisition events can be recorded by pressing the following event keys on the keyboard:

 F1-F12, Spacebar, Alt, Shift, Control

Each of these 16 keys can be assigned to an independent binary event which begins each time the corresponding key is pressed and ends as the key is released. Due to operating system limitations no more than two keys of the subset F1-F12 and Spacebar can be pressed simultaneously. The "Alt" key should be reserved for flagging points with missing object. See Inside case documents for more information on case documents and their file formats.
