### 7.4 Internal Editor

Since version 2.3 (MFC GUI) or 7.0 (CLI GUI) Msc-generator has an internal text editor integrated with the GUI. Via tracking mode, you can quickly jump to a particular element in the text, but can also quickly see, what is the result of a specific line.

In the MFC GUI there is a separate Ribbon category governing options for the internal editor. On its first pane you can toggle if you want the current line highlighted and/or line numbers displayed. The other features of the internal editor are explained below. If you accidentally close the internal editor, use the ‘`Text Editors...`’ button on the Edit pane of the Home category to turn it back on.

The CLI GUI supports the same features, but has less customization options (in `Settings`) for simplicity.
