I have a question that is maybe a suggestion. Have just changed to Windows 8.1 / Internet Explorer 11. And it seems that Internet Explorer has taken over the alt-shift-a shortcut so that it is not possible any more to call the link interface in visual editor with the assigned shortcut, alt-shift-a.
I asked Microsoft support who tells that shortcuts are not changeable in Internet Explorer, and I then tried to download your plugin, hoping that it addressed the problem.
Do you have any suggestions as to how to solve that situation, could it even be a feature of a coming upgrade of your plugin? Or should it rather be something to correct in the next upgrade of WordPress?
Alt-shift-a still works in Chrome and Firefox, so another option would be to change browser. But (probably due to many years habits) I feel that the writing process is softer and better facilitated in Internet Explorer, so I should very much like to stay with Ineternet Explorer.
