It's true that some very popular software packages define their own
Alt+key or Ctrl+Alt+key combinations, and keyboard layouts that use the
same combinations (as AltGr+key) will conflict with them. I just annoyed
a colleague the other day because my keyboard layout (John Cowan's
delightful Moby Latin [1]) co-opts one of his favorite Visual Studio
shortcuts; he tried to build a project and got U+2022 BULLET instead.

But there are also a lot of keyboard layouts worldwide that do use AltGr
keys. There are only so many keys on a standard keyboard, and if you're
designing a layout and you've made all the tough choices and you still
need to find room for more characters, you pretty much have to go to

It helps to educate users of such a keyboard layout, especially
Americans, that the left and right Alt keys aren't the same. Americans
tend not to expect this, because the standard U.S. keyboard doesn't use
AltGr at all and the key isn't marked as such.
