 Known Issues:
 -------------
 
- - ``<Esc>`` Key does not dismiss the completer and does not clear the current
-   buffer. This is an on purpose modification due to current technical
-   limitation. Cf :ghpull:`9572`. Escape the control character which is used
-   for other shortcut, and there is no practical way to distinguish. Use Ctr-G
-   or Ctrl-C as an alternative.
