You can now view the definition of a word by highlighting it and clicking on the Merriam-Webster Dictionary Lookup Button in the Netscape Communicator Links toolbar. If double-clicking does not work, try swiping the word to highlight it. If you click on the button without selecting a word, a dialog box will prompt you to select a word.
The Dictionary Lookup Button may not operate properly when used with pages that include frames or other dynamic features.
