Slideshow where one can't step back from some slides using the keyboard

Problem description:

In some LO slideshows, for some slides, the left arrow and PageUp keys don't work during presentation. It seems that this is related to an 'animation' marker of the previous slide in the left sidebar, even though that slide has no animation.

Steps to reproduce:
1. Load the attached cant_stepback.odp
2. Go to slideshow (F5)
3. Step forward a few slides with the right arrow or PageDown
4. Try to go back with left arrow or PageUp

Current behavior:
The hourglass symbol shortly apears in the bottom left corner, but it does not go back. One has to right-click and select 'previous' on the popup menu to go back.

Expected behavior:
Left arrow and PageUp keys always working for stepping back.

Same problem on Windows.
Same when using a wireless presenter instead of the arrow keys. (I think that the presenter is recognized as an external keyboard by the computer)

I suspect that an animation marker is not properly cleared. Possibly similar bug: 76700

Operating System: Mac OS X
Version: release

Comment 8 Keith 2018-04-01 00:50:55 UTC
Minimal steps for me:

create a new, blank Impress document
add a slide
add a distinguishing characteristic to each slide
set the second slide to advance automatically
start slideshow
attempt to navigate using the keyboard

On further examination, the behavior using these steps is slightly different than when loading the first attached file (I have not succeeded in downloading the second one yet, it's horribly laggy today). Is this two different bugs?
Comment 9 Keith 2018-04-01 01:32:51 UTC
Ok sorry for my hastiness, I see it is reported as a separate bug.

        I'm the reporter of the second document test.odp (through https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=759789 ).
I have the following additional observations, related to that document:

- this bug is reproduced by current testing version;

- in presentation mode, backing up from slide 2 to slide 1 can be achieved by right-clicking on the slide and using the Previous or Go to Slide buttons in the popup menu.  Apparently only the keyboard back-up is inhibited on that slide;

- the little "magic click" symbol displayed (in edit mode) next to slide 1 (but not 2) in the Slides sorter at the left proves that this "do-not-back-up-to-me" is a "transition" property of slide 1.  There may be a way, but it seems far from evident how to delete this property. To me at least.

- the same comments apply to the other example cant_stepback.odp : the slides that one cannot step back into are all marked by this little "magic click" symbol in the Slides sorter.

So the solution to this bug may be to add some "clean all transitions" button in the Slide Transition dialog, which should of course do what it promises.

Thanx a lot for any progress on this!

I would just add that any slides with video in them seem to have this issue.

Repro 6.4+. Inherited from OO.

I found a workaround that removes most of the problem: save the ODP file as PPTX, close the current presentation, and load the PPTX file. Save that as ODP (or keep working with PPTX - don't know if there are any drawbacks).

This procedure works for the two ODP files attached to the bugzilla entry.

In a 200 page Impress file, this left one problematic slide. In that slide, it had the little square with the arrow in the Animation pane. After removing that, this slide was also good.

Another partial workaround is: right mouse click, choose Goto Previous .
