Most of Interachie's Features are available for Interarchie's Main Window:
Figure: Interarchie Main Window
or from Interachie's File Menu Bar Item.
New version of Interachy (from Version 4.0 onwards) allow different Interachie Main Window interfaces. The best one to use for this course (and probably in general) is the default interface. If the window you get when you first launch Interarchie is different from above, select the Home menu from to Macintosh Menu bar (with Interachie as the active application) and select the default interface Menu Option.
The basic operations you can do are listed below. See InterArchie Manuals and online help for more details.
