title: How does one set specific vim-bindings in Ipython 5.0.0
body: <p>I understand that because Ipython 5.0.0 uses a new input library (prompt_toolkit) it no longer defaults to the editor mode specified in .inputrc (*nix). This option has to be set in an Ipython profile configuration file (see <a href="https://stackoverflow.com/a/38329940/2915339">https://stackoverflow.com/a/38329940/2915339</a>).</p>
  
  <p>My question is: having set vi-mode in the profile configuration file, how does one specify a particular keybinding? I like to use 'jk' for escape, for instance.</p>
