To create a shortcut key:

  1. Right-click a toolbar and choose Customize (Tools → Customize).
  2. Click the Keyboard button.
  3. Select a template in which to save the keyboard shortcut by choosing a template from the Save changes in list. If you choose Normal.dot, your shortcut will be global and available in all documents. Often, that is what you want.
  4. Locate the command you want to add to a toolbar by finding its menu name in the Categories column, and the command name in the Commands column. If you are unsure what a command does, click the Description button.
  5. Check to see if the command is already assigned a shortcut that you didn't know about by looking in the Current keys list. If you wish to un-assign a shortcut, select it in the Current keys list and click Remove.
  6. In the Press new shortcut key box, press the keyboard shortcut you wish to use. A shortcut key should include one or more modifiers (Ctrl, Shift, and/or Alt) and a letter or number.
    If a shortcut key is already assigned to a command, that command will appear in the Currently assigned to section. You can overwrite the default shortcuts. The goal is for Word to work the way you want it to work.
    Many of the built-in shortcut keys use the Ctrl modifier. We recommend you use Alt or a combination of two modifiers (Ctrl+Shift, Alt+Shift, or Ctrl+Alt) to create custom shortcuts. That way, you are less likely to run into conflicts where you have to overwrite an existing shortcut with a custom shortcut.
  7. Click Assign.
  8. Click Close to close the Customize Keyboard dialog box.
  9. Click Cancel or Close to close the Symbol dialog box.
