To reproduce:
- Open Wizard dialog via File/New
#1. Results of Accessibility test 
===============================================
 Tested Window title : New Wizard
===============================================
 No Accessible name :
   Class: javax.swing.JScrollPane$ScrollBar {  | } 
No Accessible description :
   Class: javax.swing.JScrollPane$ScrollBar { | } 

Components with no LABEL_FOR pointing to it :
   Class:
org.openide.awt.SwingBrowserImpl$SwingBrowser { 
Template Description: text/html } 
   Class:
org.openide.explorer.view.TreeView$ExplorerTree { 
Select a Template: |  N/A } 

#2. There is no visible indication for read-only
component "Template Description" if we push ALT-T
or tab in it.

Now, if focus in the tree and I push the Tab key -
I don't know where is focus. I push Tab again and
result is the same. Afher pushing in the third
time I hear a beep and guess that I is in 
the textarea and need to prees CTRL-Tab. 

So, the text should be selected, if it gains focus
and de-selected if focus moved out. It is very
convenient for a user. The dialog will become more
user friendly.
