macOS specific override for the shortcut to select the word currently under the caret.

If no selection is currently active with the last caret in text fields, searches for the next occurrence of the the word currently under the caret and moves the caret to the next occurrence. The action can be performed sequentially for other occurrences of the word under the last caret.
If a selection is currently active with the last caret in text fields, searches for the next occurrence of the selection, adds a caret, selects the next occurrence then deselects the previous selection and its associated caret. The action can be performed sequentially for other occurrences of the selection of the last caret.
The viewport is adjusted to the latest newly added caret.
