Shortcut to insert row in Excel
Just tested command shift + and control shift + on excel 2016 on a mac - both add a row as long as the row is selected.

If the row is not selected then it will shift the cells down in that row.

For Excel 2011, then control i works to add a row if the row is selected, if only a cell is selected then it brings up the insert cell dialogue.
In excel 2011 command i does italic.

For command-shift-i this does italic on the selected row - the version using control does not work (excel 2106).

That website has information that appears out of date.
