Creating multiple empty slides at once.

Create an additional slide. Then select both of the slides and copy them.

Paste those two slides underneath the two existing ones. Now you have four slides.
Copy them and paste them underneath the existing four etc. etc.

How to make a Table of Contents in LibreOffice

You can do it in two ways: manually or automatically.
In this text only the manual way is discussed.
These are the steps to be taken:

In the text itself you select and bookmark the headings that you want in the Table of Contents. (Select text/Insert/Bookmark)

Then add the text that you bookmarked to the Table of Contents. When you have done that,hyperlink the text of the table of content to the bookmarks (Insert/Hyperlink/Document/Target).

It should look like this:

Shave his belly with a rusty razor (this text is hyperlinked to the bookmark)

Put him in a longboat till his sober

Stick him in a barrel with a hosepipe on him

Put him in the bed with the captains daughter

And the original text:

What will we do with the drunken sailor

What will we do with the drunken sailor

What will we do with the drunken sailor

Early in the morning

Way hay and up she rises

Way hay and up she rises

Way hay and up she rises
