<ul class="simple"><li>It is only possible to edit one line of text at a time. When using the <strong>readLine</strong> method, it will not be possible to physically go to the next line (this simplifies things a bit...).</li>
<li>No UTF8 support, only ASCII characters are supported.</li>
<li>No support for colorized output.</li>
<li>Only limited support for Emacs keybindings, no support for Vi mode and Vi keybindings.</li>

<p>If a <strong>completionCallback</strong> proc has been specified for the current editor, attempts to auto-complete the current line by running <strong>completionProc</strong> to return a list of possible values.
