So, I’m making a game in Libreoffice impress (dont ask) and its a choose your own adventure style game. I just need to know how to make it to where users cannot go to the next slide on certain slides, so they can only click on the option. I also plan to support powerpoint, so will the settings carry over to powerpoint when saving as .pptx?
Remove:Slide Show > Slide Show Settings >Presentation Options > Change slides by clicking on background in the Menu.
when saving as .pptx?
Save only inOPTODP and then copy to pptx.

OPT the new ODF for puzzle games? 
Users can always manage a running presentation with the keyboard, see section “Shortcut Keys in Slide Shows” in Shortcut Keys for LibreOfficeDev Impress
The shortcut keys are necessary for the accessibility-promise of LibreOffice, to be usable without mouse.
should be possible to inhibit with sth like Fatal Error in KeyHandler_keyPressed, an uninitialised event object? - #7 by Ratslinger
strangely enough, somehow duplicated in Using Shortcut Keys in LibreOffice Impress
Yes, but users can still use keys (Enter, arrows, etc) How do I remove that
