Unhide all cells in Google Colab

Question

Is there a way to unhide all hidden cells in a Jupyter notebook on Google Colab?

It appears that google colab hides cells automatically. Is there a way to unhide all cells? It's a pain to click each hidden cell especially when they are nested. And I sometimes inadvertently skip over hidden cells when reviewing a notebook.

Answer 1

This worked for me to expand all Colab hidden cells. Both from the menu:

1. Edit --> Select all cells

2. View --> Expand Sections
