Custom Keywords are a powerful feature which enables you to create your own personal keywords which you can type into the location bar for quick access to your favorite sites. Here is how you can use this feature (this assumes that you have already created a bookmark for the site you are interested in; in this example we will use Google as the bookmarked site):
First: Select Bookmarks – Manage Bookmarks. This will open the Bookmark Manager.

Second: Select a bookmark in the Bookmark Manager menu by right-clicking on bookmark. Select Properties in the drop down menu to access the Properties Menu.

Third: Type a keyword of your choosing into the Keyword box in the Properties Menu. In the example below, the keyword has been set to google, but you can choose any word you like. Based on this example, you can now type google into the Location Bar to immediately access the Google website.
