I'm trying to insert references into a
beamer footline. These references are different for each slide, so I cannot include them in the footline template – unless there is then some way to later define them per-slide.
I have tried to simply include the after a
\vfill, but the location of the line then varies with each slide, and this is not what I want.
How do I insert references (or really, just any custom text) into the footline of a specific slide in
