Keys are named with an a prefix, as in <a-f> for alt and f keys. Also note that the old mechanism for alt keybindings on 8-bit terminals still works as before.

- cmd-word with <a-f>
- cmd-word-back with <a-b>

- cmd-uppercase-word with <a-u>
- cmd-lowercase-word with <a-l>
- cmd-transpose-word with <a-t>

(Fix) History selection is disabled when a piping shell command is running.
