            Bug ID: 143732
           Summary: Right/left arrow behaviour in presentations is
                    unpredictable
           Product: LibreOffice
           Version: 6.4.7.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: geoffrey.lee.dadswell at gmail.com

Description:
When advancing/rewinding a presentation using keys, sometimes animations are
skipped and the presentation advances to the next slide unexpectedly.  Backing
up from one  slide to the previous  one unexpectedly rewinds some animations on
the previous slide.

Steps to Reproduce:
1. Create a new Impress document.  Don't select a template, just cancel the
template dialogue so you have a blank presentation.
2. Edit the title, and text on slide 1, then insert two or more objects
(textboxes, images, doesn't seem to matter what).  Add animations to these two
objects to make them appear, each on their own click.
3. Create a second slide.
4. Start the presentation at the beginning.  Advance through the presentation
using right arrow.  Everything should behave as expected.
5. Go back to the beginning of the slide show (e.g. left arrow until you are at
the start).  Right arrow  once to run the  first animation.  Left arrow once to
undo it.  Now  right arrow twice.  It will run the first animation, but then
will skip the second animation and advance to the second slide.
6. Try right and left arrow in various sequences.  This should cause some
unexpected behaviour such as running two animations on one click, or backing up
from slide 2 to slide 1 but with not all the animations on slide 1  in their
final states.

Actual Results:
Right and left click inconsistently advance and back up, sometime launching  or
undoing  more than one event.

Expected Results:
Right arrow should always advance  one animation.  If all the animations on a
page have run then right arrow should advance to next slide.  Left arrow should
always back up one animation.  If the presentation  is on slide 2 (with no
animations on that slide) then left click should back the presentation up to
slide 1 with all animations there having already run ("final state" of the
slide).


Reproducible: Always
