As you might guess, the ``d'' command is responsible for deleting text. To delete text, we need to combine the delete command with a command saying how much to delete: a word (dw), a line (dd (or D)). Non-intuitively, to delete a single character is ``x'', to delete n characters is nx. If you want to delete the character in front of the cursor (a destructive backspace), the command is ``X''.
