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
kern
feature when the font is generated.If a
kern
feature 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.
