How to know whether contextmenu item was selected by mouse or shortcut?

I have a uitable that I add/delete rows from using context menu selections. I have the ability to use the mouse and select the contextmenu or just CTRL+ "N" or "Z" to add/delete rows. Is there a way to know whether the callback for that menu selection is triggered by my mouse vs. the shortcut?

The problem I run into with the code below is if a user selects a cell in row 1, but then uses the mouse+contextmenu on a cell in row 2, the table.selection property is not empty so the code below thinks my user selected row 1.

if ~isempty(app.SequenceTable.Selection)
    temp = app.SequenceTable.Selection;
    row = temp(1);
else
    row = event.InteractionInformation.Row;
end

I previously flipped it so my if statement had the condition below, but that caused a similar problem the other way.

isprop(event,'InteractionInformation')

One potential improvement that may work is looking at the current modifiers for the main figure:

if ~isempty(get(app.Main_UIFigure,'CurrentModifier'))
    temp = app.SequenceTable.Selection;
    row = temp(1);
else
    row = event.InteractionInformation.Row;
end

This works for normal user input, but if someone decides to hold the CTRL button while they right-click and select an item from the context menu, then it will return the row as the currently selected cell rather than the one that was right-clicked on.

Looked around some more and I think my best proposal for this problem is to use the SelectionType of the app's main figure:

if strcmp(app.Main_UIFigure.SelectionType,'normal')
    temp = app.SequenceTable.Selection;
    row = temp(1);
else
    row = event.InteractionInformation.Row;
end
