MTEXTED (System Variable)

Sets the application for editing multiline text objects.

Type: String
Saved in: Registry
Initial value: "Internal"

You can specify a different text editor for the MTEXT command. If you set MTEXTED to internal or to null (.), the In-Place Text Editor is displayed. If you set MTEXTED to "OldEditor", the Multiline Text Editor is displayed. If you specify a path and the name of the executable file for another text editor or word processor, that path and file name instead are displayed instead.

Text editors other than the internal one show the formatting codes in paragraph text.

Note: Starting with AutoCAD 2022, the expected encoding of the output from the external editor can be specified using the MTEXTEDENCODING system variable.
