No option to insert page break in Calc

I am running LibreOffice

The Menu bar in Calc offers File Edit View Insert Format Sheet Data Tools Window and Help - which is not the arrangement shown in YouTube videos such as (where the bar runs … Format Tools Data Window Help). On my “Insert” menu there is no “Manual Break” option. (I can’t upload a screengrab since I don’t have the points.)

I have looked through all the “Customise” options and none of the available additons include “Manual Break” or anything similar.

Do I need to add a plug-in?


with LO~5.1 some Menu-Entries has ( IHMO - unfortunatly ) moved.
it now →Sheet→Insert Pagebreak…[Rowbreak|Columnbreak]
