Some C<read-line>s have predefined values. You can access these values with the C<Up-Arrow> and C<Down-Arrow> keys.

To exit a C<read-line> without returning anything, press C<Ctrl-X>. When the input buffer is empty and C<Enter> is
pressed, C<read-line> returns an empty string.

The elements are right-justified if they look like a number; otherwise, they are left-justified.

If the option I<squash_spaces> is enabled, leading and trailing spaces are removed from the elements, and spaces are
squashed to a single white space.

Tab characters (C<\t>) are replaced with a space.

Vertical spaces (C<\v>) are squashed to two spaces.
