reverse-search-history is bound to C-r by default. One can type C-r to start the search, and then type C-r again to jump to an earlier match.
I have bound
reverse-search-history to \er (Alt-r). This new binding works for the initial search, but subsequent presses of Alt-r don't continue searching. C-r seems to still be needed to repeat the backwards search.
Is there a way to make Alt-r work for the repeat function as well? Or a way to bind the 'continue searching' function to any key other than the default? I was able to do it in emacs, but couldn't find any relevant documentation for bash/readline.
