===How can I get the position of the caret in the currently selected editor window?===

You need to first get the selected node (which if the Editor is selected, should correspond to the file being edited); get the most recent editor pane open on it; and then access the caret:

&lt;pre&gt;
Node[] n = TopComponent.getRegistry().getActivatedNodes();
if (n.length == 1) {
    EditorCookie ec = (EditorCookie) n[0].getCookie(EditorCookie.class);
    if (ec != null) {
        JEditorPane[] panes = ec.getOpenedPanes();
        if (panes.length &gt; 0) {
            int cursor = panes[0].getCaret().getDot();
            String selection = panes[0].getSelectedText();
            // USE selection
        }
    }
}
&lt;/pre&gt;
Or
&lt;pre&gt;
org.netbeans.api.editor.EditorRegistry.lastFocusedComponent().getCaretPosition()
&lt;/pre&gt;

===How can I get the linenumber/column of the currently selected editor?===

&lt;pre&gt;
        JTextComponent editor = org.netbeans.api.editor.EditorRegistry.lastFocusedComponent();

        //using StyledDocument
        {
            StyledDocument sdocument = (StyledDocument) editor.getDocument();

            int line = NbDocument.findLineNumber(sdocument, editor.getCaretPosition());
            int column = NbDocument.findLineColumn(sdocument, editor.getCaretPosition());
        }
        //using BaseDocument
        {
            try {
                BaseDocument bdocument = Utilities.getDocument(editor);
                int line = Utilities.getLineOffset(bdocument, editor.getCaretPosition());
            } catch (BadLocationException ex) {
                Exceptions.printStackTrace(ex);
            }
        }

&lt;/pre&gt;
