To see all of the shortcuts that you have created on your site as well as any reserved shortcuts that the system already has, navigate to http://www.yourdomain.org/siteshortcuts.aspx.
To edit a Shortcut:
- Editing the page.
- Click on the Display tab.
- Edit the Shortcut field.
If you can't do this, it means that the Shortcut is a system generated reserved Shortcut. We can not change these as everyone uses these shortcuts.
