New command
The New command opens the necessary windows to work with new, empty documents. Mira supports only one type of empty document, which is for text files. With the basic Mira software, the single choice in the New Documents window opens a Text Editor containing a fresh, empty text document. If you have the Pro Script module, the New Document dialog also shows a Script Document option which creates an empty script in the Script Editor.
Open the New Document dialog from the File Menu.
