moveWordForward: on ⌥-f in El Capitan doesn't repeat I've used Jacob Rus' cocoa text system bindings for many years to give me more emacs like bindings in cocoa text fields (apple doc here. Since El Capitan I find that option-f which does moveWordForward: only works once and doesn't repeat if I hold down the keys. option-b (moveWordBackward:) does repeat as it always has and so does option-rightarrow (which I assume also does moveWordForward:).

I played with KeyBindingsEditor and found that option-control-f is bound to moveWordForward: in /System/Library/Frameworks/AppKit.framework/Resources/StandardKeyBinding.dict and it repeats (also that option-right is bound to moveWordRight:). It also confirmed that option-f is bound to moveWordForward: in the Standard and my user KeyBinding.dict.

I've checked for other bindings on option-f in System Preferences and haven't found any. Anyone know what might be wrong or how I can debug this further?

Turns out a new keyboard fixed it.
