Eddie typed a word, used the undo command, and then decided he really wanted to keep the word. eddie should use the undo command again select the redo command click on the undo command twice select the paste command

Sense Eddie clicked the undo command he wouldn't want to click it again, if he does more words will leave. Sense he did not copy the word, he cannot paste it. And if he would press Undo twice, then that would take him back further, so what he wants to do is click the redo command.

Hope this helps.
