Terms Used in the Terminal Command Descriptions

In the descriptions of several terminal commands, the terms "screen" and "window" are used with the following meanings:

Term Meaning
Screen Depending on the operating system under which Natural is running, "screen" refers either to the entire terminal screen as such, or to the operating-system window in which the Natural session is running, or to the Natural main output window.

However, for the sake of convenience, the term "screen" is used in all these instances.

Window Always refers to the Natural window (as explained with the terminal command %W).
