Some keys auto-repeat, some don't #26

E.g. i & n repeat, j & k don't

The auto-repeat event for those keys does reach the KeyDown handler, and I am passing it to InterpretKeyEvents as Apple documents, but this method in turn never calls the InsertText for those characters.

The text system in macOS does not repeat keys by default, at least when the responder conforms to NSTextInputClient. This can be controlled via the ApplePressAndHoldEnabled default. You should be able to set this default to false for the bundle in the app delegate (probably in applicationWillFinishLaunching).

You can see the behavior change by disabling/enabling the default globally and [re]launching TextEdit.app. When enabled, keys will not repeat. When disabled they will repeat.

defaults write -g ApplePressAndHoldEnabled -bool false

IIRC, Apple turned off key repeating by default to facilitate the popover UI for selecting diacritical marks. For example, long press e and press 2 and é will be inserted via InsertText. That is, disabling ApplePressAndHoldEnabled effectively disables the diacritical mark input method.
