Each section lists the available shortcuts, along with their corresponding keyboard keys. For example, the "Find" section lists the shortcut "Ctrl/Cmd - F" to find an element, while the "Edit" section lists the shortcut "Ctrl/Cmd - A" to select all elements.
The article also provides a note at the end, mentioning that Chrome users who use a trackpad can also use pinch to zoom.
