How to use keypress callback and datacursor mode together in app designer?

I have a matlab app created using app designer. I want to use datacursormode in order to update the datatips on different plots that I am using, but when I enable datacursor mode my KeyPressFcn callback stops responding. Anyone have this problem and find a solution?

Hello @Leah Samet, I found a solution that it may be helpfull for you or other people. The problem is that once the datacursor mode is enable, the KeyPressFcn is blocked. So, if you want to continue using the KeyPressFcn and at the same time move the data cursor, you can use the following code:

    function UIFigure2KeyPress(app, event)
            key = event.Key;
            app.cursor = datacursormode(app.UIFigure2); %this line can alse be in the startupFcn
            if key(1)=='r' %"r" stands for rightarrow
                app.cursor.Figure.CurrentObject.Children.DataIndex=app.cursor.Figure.CurrentObject.Children.DataIndex+1;
            elseif key(1)=='l' %"l" stands for leftarrow
                app.cursor.Figure.CurrentObject.Children.DataIndex=app.cursor.Figure.CurrentObject.Children.DataIndex-1;
            end
    end
