Usability issue in plugin

I have recently switched to this plugin from another nofollow plugin. But observing it’s very difficult to work with keyboard shortcuts with this plugin. If I select the text and press CTRL+K the link window appears normally. But the issue is that the link input box is not selected by default. I have to manually click on the link input box for typing the URL. It is not user-friendly to switch between mouse and keyboard so frequently as my blogs are having plenty of internal links. If I switch to the old plugin the issue resolves.
