Comprehensive help on all aspects of the VIS software is readily available via this menu or by pressing the F1 shortcut key. Help is in the standard Windows™ format with Contents, Index, and Search options. In addition, if the F1 key is used to access help, help is context-sensitive and the portion of the help file corresponding to the current operation in VIS is automatically displayed. For dialog boxes, pressing the question mark button in the upper right-hand corner of the window caption bar also provides context sensitive help. See the Using VIS section of this manual for additional information.
