Hello zel...
I produced this a while ago, but I think I took the shortcut keys list from the MLO manual (list of "hot keys"), whereas the hotkey list I took from the Tools-Options-Hotkeys menu in MLO itself. A lot of the configurable hotkeys in the options list overwrite the default shortcut keys, but not all of them do. So, in column H you can look at the default values for the ones which get overwritten or you can filter out all the default ones which are overwritten by your personal hotkey settings.
The Line No. (column B) tells you what order these are listed in the hotkey settings list and the shortcut key helpfile list, so you can re-sort the Excel list to match.
Hope that helps and doesn't add to the confusion. Remember, though, this might not exactly match the current lists in MLO options and the help-file, as I produced this quite a long time ago.
