Can't find insert cells in the menu

I can’t find the insert cells command in my menu. The insert cell button doesn’t appear neither.
Anybody got any idea why.

Libreoffice Version:

Hello @pepforce,

the “Insert Cells…” command is supposed to be in the menu “Sheet”, ( "Sheet : Insert Cells..." )

The default shortcut key for this command is CTRL +

Also a handy toolbar button with 6 options for inserting cells, could be added to your Toolbar using the menu " Tools : Customize..." ( Tab “Toolbars”, click “Add Command”, Category=“Insert”, Command=“Insert Cells” ).
