Beamer class: question and comment

[Rich Shepard]

I hope you're all healthy, productive, and safe and you stay this way.

Question:

After years of beamer presentations with different looks I've decided on one
that I'll use for all future presentations. How do I save this format and
structure (stripped of presentation-specific content) as a default template
for all my future beamer documents?

Comment:

A just-completed presentation has 6 images in it. The first two share their
frames with text so I used columns and two individual columns per frame with
the image on the left and the text on the right. This worked just fine.

But, the next 4 images are large and each occupies an entire frame by
itself. I inserted the first one, tweaked the size and position, and used
alt-p/shift-enter to create a new frame environment. But, nothing happened;
no new frame. I looked in the beamer manual but the word 'image' appears
only once and in reference to using overlays.

After much futzing I discovered a solution. When I defined a new frame
environment I inserted an itemize environment, then immediately created a
new, following frame. With the latter patiently waiting I inserted the image
in the first new frame, set its size and position, then moved to the next
frame that was created before inserting the image.

I hesitate to call this a bug because I don't know if there's a way I've
missed to insert only an image in a frame then create a new frame after that
other than what I did.
