Found it. The Right arrow will do this.
Does anyone know what keyboard strokes I use to run a report once it is selected? I tried Enter and that is not doing anything. I can double click my mouse and that works. But you are not supposed to use the mouse in a macro.
Once you have the list of reports, try and highlight the required report and hit the SPACE bar, this will give you the Report Menu where you can choose R for Print.
Happy New year.
