Yesterday’s Mother Goose and Grimm, featuring the computer dogs (the bull terrier Grimm at the keyboard, the Boston terrier Ralph advising him):
To understand this strip, you need to know about keyboard shortcuts on a Mac computer, in particular the combination
Command-Z: Undo the previous command. You can then press Command-Shift-Z to Redo, reversing the undo command.
⌘-Z undoes, or reverses, keyboard actions. In the cartoon, the dimwitted Ralph suggests using this computer key combination to reverse events in general — in this case, the falling of the lamp to the floor and the breaking that resulted from the fall. ⌘-Z will fix it!
If only.
