In order to select your definitions click on the small black arrow next to the Dictionary icon on the Read and Write toolbar. This should reveal a short menu from which you can select your preferred definition set.

The quickest way to use the dictionary is to highlight a word that you want to look up (via click-and-drag or a double click). Then click the Dictionary icon on the Read and Write toolbar or press:

CTRL + ALT + F

If you are using Basic or Advanced Definitions the Dictionary dialog should appear in the middle of your screen. If one or more definitions have been found they will be listed on the left hand side.

To hear a definition read aloud simply click on that definition and then on the Play button on the Read & write Toolbar or press:

CTRL + ALT + Down Arrow

The dictionary will look up definitions for all possible meanings of that word. As you click on a definition you should notice a small blue rectangle indicating which type of word it is: noun, verb, adjective or adverb.

You can restrict the results to certain types of words by selecting the appropriate radio button. If the radio button you want is greyed out then there is no definition of that type for that word.

For each definition Read and Write will attempt to list some words which have a similar meaning (although I have noticed that occasionally it lists wholly inappropriate words that have nothing in relation to the original word). Double clicking on one of these synonyms will (if possible) insert it into your document.
