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:
“Show me one thing here on earth which has begun well and not ended badly. The proudest palpitations are engulfed in a sewer, where they cease throbbing, as though having reached their natural term: this downfall constitutes the heart’s drama and the negative meaning of history.”
—E.M. Cioran (b. 1911)
“The rest to some faint meaning make pretense,
But Shadwell never deviates into sense.”
—John Dryden (1631–1700)
