The text contains certain symbols. Clicking on these symbols makes additional information appear.
The symbols indicate what kind of information is available.
 |
Charts showing the relationships between units in a system,
such as inches, feet and furlongs. Try this example: |
 |
Maps. Clicking on this symbol will bring up a map showing the location of the place whose name came just before the character. If the area of the location is too small to be easily seen on a map big enough to show familiar features, the first map shown will contain a red box. Click within the red box to bring up a map of the area covered by the red box. |
 |
Footnotes, which are usually citations of sources: the names of authors and titles of their books or articles. This symbol is a bad idea from a period when we thought footnotes should appear in pop-up windows. Now that many people have disabled popups in their browsers, we are phasing out the symbol in favor of old-fashioned, printable footnotes. |
 |
Conversion. Clicking on this symbol starts a program that can convert measurements to and from the unit whose name immediately precedes the symbol. It is also used to bring up a program that converts dates from one calendar to another. |
 |
Pronunciation. If your computer has a compatible sound card, clicking on this symbol will produce the sound of the word immediately preceding the symbol. Except for words in extinct or rare languages, all the pronunciations have been recorded by native speakers of the language. |
 |
Digging deeper. A fuller or more detailed explanation. For example, when a sentence that says “most x are y…” or “the Z is usually…” is followed by this symbol, clicking on the symbol takes you to a page that usually explains the nature of the exception. |
