The Notes major menu contains a number of commands that enable the user to maintain three-dimensional notes in the database. Such notes are useful is for tracing a new structure when one often wants to record ideas of where one may be in a structure, for introducing reminders during refinement, or for taking pictures.Each note has an associated name, and can contain an arbitrary number of text elements. Any number of objects can be generated from the notes. The colour and size of the text elements can be adjusted (SGI machines don't support different text character sizes). A text string can be added next to an ID'ed atom, or at a specific coordinate in orthogonal Ångstrom coordinates. When created, a text string will be added to the currently open note name and note object. However, to avoid the screen from getting cluttered with a large number of 3D text strings, that also degrade the performance of the graphics system, the display of notes can be restricted to those within a given radius from the active centre. Presently, note objects are not recreated when the program is started.
