For my presentation I am using the
beamer package. I added frames that include my personal notes that only appear when I am compiling with the handout-option.
On this handout I would like to include a sign on each slide that indicates whether it is being shown in the presentation (when compiled with the presentation mode) or not so that I have a quick overview when I am looking at my printed handout. Such a sign could be a bold "B" in the top right corner.
How do I implement this?
