Sometimes there will be too many mistakes
to attempt to correct each one. If this should happen it may be easier
or quicker to just erase the whole card and start over. To do this
select "Edit"
"Delete Card" as shown below.
HyperStudio will then ask you if you want to delete the entire card, click
"Yes."

You should now have a blank card in front of you. If you happen to choose "Delete Card" by accident simply go under "Edit" and select "Undo Deletion," your deleted card will reappear. You must do this before any other action is taken because HyperStudio is not like the newer versions of Microsoft's Word in that you can undo a great many actions. HyperStudio will only let you undo the last action taken.
