Features Editor ↩
The Features Editor is a simple code editor for writing OpenType features using the AFDKO feature syntax.

If you kern using Kern Center or MetricsMachine, the kerning data is stored in the font’s kerning dictionary, and will be converted automatically into
kernfeature when the font is generated.If a
kernfeature is defined in the features, it will override the font’s kerning dictionary.
See Tal Leming’s OpenType Cookbook for a designer-friendly introduction to developing OpenType features.
Linking to external feature files
The Features Editor supports linking to external .fea files using the include statement:

include(features.fea);
The editor also supports drag-and-drop of .fea files. The dropped file is inserted as a link to the external .fea path.
Editing stand-alone feature files
RoboFont supports .fea as a native file format. Double-clicking a .fea file will open it in a separate Feature Editor which is not connected to any UFO.
