Layout of Key Bindings

This might be nitpicking, but currently the layout of the key bindings is not easy to read. The current list could be improved by e.g. inserting vertical lines or alternating colours as it is not easily visible where one entry ends and another one starts. Additionally, as a User I got confused by the short-cut standing in the front row and what it does as indent. I would have expected this the other way around, as the user usually knows what action he/she wants to search for and not the keys for this... In case the user slips in the row and accidentally uses the keys for the action above or below, this can in the worst case end in an unplanned deletion of all trajectories...
