Prevent slide transition with keyboard only?

Hi,

can one setup the slide transition so so one can’t with click on any key of keyboard to get the next slide?

I want this behavior because I’m using ‘Interaction’ on graphical objects on slides to move to the specific slide.

Or, how to get this facility: how can one navigate not to the next slide but to some other slides with keyboard too?

I hope I was clear…

I find the solution: by using the Custom Slide Show.

However, I don’t understand, how can one uses these custom slide shows in one presentation?
How can one start say within one custom slide show a second custom slide show?

at here how to start the [ Custom Slide Show 2. ]
