3. Select the key that you want to map from the column on the left and choose the key that you want o map it to from the column on the left.
4. Click "Write to registry" and either logout or restart the computer to commit the changes.

To remove this prank, just open up the Sharpkeys program again and select the keymap you created and hit the "Delete" button. Then hit Write to Registry and restart again.

Step 2: Change "Autocorrect" Settings

This prank changes the settings in the Autocorrect feature found in Microsoft Word or Microsoft Outlook:

1. Open up Microsoft Word or Outlook and find the Autocorrect settings in options (the location of it varies depending on which version you have).

3. When you have created an autocorrect rule, click the Add button and then click OK.

Now when anyone types the word "the", it is going to be replaced by "idiot" automatically. To remove this prank, just remove these rules from the autocorrect settings.
