### 6`` Editor Modes

DrScheme provides support for multiple editor modes. Tools register modes via drscheme:modes:add-mode. Each mode is visible in the Modes submenu of the Edit menu. Initially, DrScheme only supports two modes: scheme mode and text mode.

DrScheme automatically selects a mode for each open file based on the file’s extension. If the file ends with .txt, DrScheme uses text mode. Otherwise, DrScheme uses Scheme mode.
