Meaning
The meaning of the key's abbreviation is not explicitly given in many IBM PC compatible technical reference manuals. However, IBM states that AltGr is an abbreviation for alternate graphic, and Sun keyboards label the key as Alt Graph.
Apparently, AltGr was originally introduced as a means to produce box-drawing characters, also known as pseudographics, in text user interfaces. These characters are, however, much less useful in graphical user interfaces, and rather than alternate graphic the key is today used to produce alternate graphemes.

Famous quotes containing the word meaning:

—Ezra Pound (1885–1972)
“In our definitions, we grope after the spiritual by describing it as invisible. The true meaning of spiritual is real; that law which executes itself, which works without means, and which cannot be conceived as not existing.”
—Ralph Waldo Emerson (1803–1882)
