Usages for the Text editor

The Text editor is handy also when you want to share your blend-files with others. The Text editor can be used to write in a README text explaining the contents of your blend-file. Be sure to keep it visible when saving!

Footer

The Text editor footer displays if the text is saved internal or external and if there are unsaved changes to an external file. For external files, this region also displays the file path to the text file.

Usage

Running Scripts

The most notable keystroke is Alt-P which makes the content of the buffer being parsed by the internal Python interpreter built into Blender. Before going on it is worth noticing that Blender comes with a fully functional Python interpreter built-in, and with a lots of Blender-specific modules, as described in the Scripting & Extending Blender section.
