What does alt do on a keyboard?

Answer 1

They are used for advanced Dual key usage,

Answer 2

The function of the "Alt" keys hasn't changed much, they are still used for the same purpose as they did when they were first introduced.

They allow multiple combinations of keys in a sequence to achieve different results.

"Ctr Alt Del" is different from "Ctrl Esc", "Alt F4" is different from "Ctrl F4" and so on.

Back in the early days when there were no mice you learnt many different key sequences to work more efficiently. WordPerfect 5 and below used "F7" for exit, but "shift F7" for print, and "Alt F7" for columns/Table.

In Windows "Alt Tab" switches between programs, but in Linux "Ctrl Alt (1-9)" changes to a different prompt window.
