 `nnn` uses libreadline for the chdir prompt input. So all the fantastic features of readline (e.g. case insensitive tab completion, history, reverse-i-search) are available to you based on your readline [configuration](https://cnswww.cns.cwru.edu/php/chet/readline/readline.html#SEC9).
 
+#### work faster at rename prompt
+
+The rename prompt supports some bash-like command-line shortcuts - <kbd>^A</kbd>, <kbd>^E</kbd>, <kbd>^U</kbd>. <kbd>^L</kbd> clears the name.
+
 #### set idle timeout
 
 The terminal screensaver is disabled by default. To set the wait time in seconds, use environment variable `NNN_IDLE_TIMEOUT`.
