Footnotes

(1)

This usage of “key” is not related to the term “key sequence”; it means a value used to look up an item in a table. In this case, the table is the alist, and the alist associations are the items.

(2)

This definition of “environment” is specifically not intended to include all the data that can affect the result of a program.

(3)

See the documentation for ‘set-input-mode’ and ‘set-console-tty-coding-system’ if you’re having trouble inputting non-ASCII characters in the TTY.

(4)

Be aware that higher values (say, above ‘\1000’) risk the matching code throwing an error when it runs out of stack space, and that GNU Emacs does not currently (2023) support values greater than ‘\9’.

(5)

Not quite the case; the result of the functions are pre-calculated and cached whenever define-specifier-tag or make-charset is called.

(6)

That’s what the standards call it, though my North American readers will be more familiar with it as the period character.
