# Hide both input cell and output cell

You can double-click the right gutter of a input cell to hide a corresponding output cell or double-click the gutter of the output cell to hide the input cell.

I would like to hide both the input and the output cell. Is this possible to do within the GUI?

It can also be done using the Option Inspector (Shift+Ctrl+O on Windows), or programmatically with e.g. SelectionMove and SetOptions.
