Enabling the 'show-copy-button' option adds the 'copy' button to the toolbar.
Enabling the 'show-copy-button' option adds a 'copy' button to the toolbar.
This is just of the one examples, but I came across similar sentences relatively often. On one hand, there are multiple buttons, and you are adding another kind of a button, just like every other button. Perhaps this button can even be configured such that it can be basically the duplicated version of an existing button.
On the other hand, the exact 'copy button' refers to a specific thing.
So which is it?
Thanks in advance.
