I connected an external Logitech wireless USB keyboard to a MacBook Pro. Generally the keyboard works fine. But the Insert key (present on this external keyboard, is not present on the MacBook's built-in keyboard) and does literally nothing.

Even in the Ukelele application (a keyboard layout editor) this key does nothing.

Short question is: How to make this key visible to macOS?

Long question is: how to make this key work in following use cases:

  1. VIM running in terminal: switching COMMAND/INSERT/REPLACE modes.

  2. Using SHIFT+INSERT for inserting text from clipboard in any application.

Note: I know how to do (1) and (2) by other ways, like command+V for insert and i/R in VIM. That's not an issue here. The issue is only the usage of a very handy INSERT key.
