Thank you for the detailed description.
I have investigated the issue but due its complexity, I can not provide you with any workaround.
I have logged the issue into our system and here is the feedback item
where you can track its status and vote for it.
In Q1 2014 which will be released at the end of February 2014, we will improve the TrackChanges commands tracking functionality and we will probably consider the keyboard support for the planing for Q2 2014.
As a small token of gratitude for reporting this issue I am updating your Telerik points.
Please excuse us for the caused inconvenience.
