So you know this "secret" and almost not used shortcut to "delete" instead of backspace while on a text editor? The Fn+Delete keys would delete words from left to right instead of the other way around with the single delete key. For me it was really useful as "Delete" is missing on my keyboard, but now with macOS Sierra, I can't do it anymore. Now, instead of deleting the following character to the right of the cursor, it starts backspacing nonstop until everything goes away. I'm not sure if it's a bug or this just changed or went gone. Is anyone struggling with the same issue here?
