I mistakenly collapsed cards on a Trello board and cannot find the command to restore the display

[DaveA MDM]

Before i made the mistake, all cards were displayed in all categories.  After the mistake, no cards are displayed, only the category topics at the top of the board, with a number of cards noted in each category. 

This command affected only the Trello board that was displayed.  Other Trello cards on other boards have remained fully visible.

Seeking the command to reverse my error.

Hit the x key on your keyboard.  Or at the top of the board there is an X on the part showing you the filter you have applied to the board.
