public void setEnterKeyForwarding(boolean forwardEnter) {
		this.forwardEnter = forwardEnter;
	}
HACK ALERT:  By default, the JComboBoxUI forwards the &lt;Enter&gt; key actions to the root
pane of the JComboBox's container (which is used primarily by any installed 'default
button'). The problem is that the forwarding does not happen always.  In the case that the
&lt;Enter&gt; key will trigger a selection in the combo box, the action is NOT forwarded.
<p>
By default Ghidra disables the forwarding altogether, since most users of
{@link GhidraComboBox} will add an action listener to handle &lt;Enter&gt; actions.
<p>
To re-enable the default behavior, set the <code>forwardEnter</code> value to true.

@param forwardEnter true to enable default &lt;Enter&gt; key handling.
