You can find help on many of the different options in MEC here. By selecting an item in the left side of the help display, which works in the same manner as the standard open box, the appropriate help text is displayed in the right hand side of the help window. You may scroll through the help using the scroll bar. The help will not disappear until another help item or the Cancel button is selected. To save space on the disk, the help file can be removed, but this results in not having any on-line help during the execution of the program.
