Wrong tags in a11y guide newly added section

[Luca Ferretti <elle uca libero it>]

Hi,

I've started to update the Italian translation for the accessibility
guide and I've found the following wrong tags:

        gnome-access-guide.xml:7(para)
        <keycap>Alt-F1</keycap> - display and activate the GNOME Desktop
        menu bar. This grants access to the
        <guilabel>Applications</guilabel>, <guilabel>Places</guilabel>
        and <guilabel>System</guilabel> menu bar items.
        
<keycap>Alt-F1</keycap> should be
<keycombo><keycap>Alt</keycap><keycap>F1</keycap></keycombo>

<guilabel> should are <guimenu>

        gnome-access-guide.xml:15(para)
        <keycap>Alt-F2</keycap> - summons the <emphasis>Run</emphasis>
        dialog, where you can issue terminal commands with or without
        parameters. If a file needs to be passed as one of these
        parameters, use the <guilabel>Run With File</guilabel> button to
        easily locate the file needed. This dialog also presents an
        alternate list of known applications which may be easier to
        navigate for some than the typical <keycap>Alt-F1</keycap>
        approach.

Again, missing <keycombo> plus: <emphasis>Run</emphasis> should be
<application>Run Application</application> or similar (I've to check
user guide); <guilabel>Run With File</guilabel> should be <guibutton>.

Note in this section there are a lot of simple <keycap></> instead
<keycombo><keycap></></>, I'm not reporting all of them.

Is it OK let me fix them on svn?

PS note also that
1) For Solaris systems, this key is <keycap>Ctrl-Esc</keycap>
  * s/key/shourtcut,keybinding ??

2) For Solaris systems, this key is <keycap>Meta-R</keycap> (as with
Microsoft Windows). A meta- or super-key is an OS-logo shift key
  * as above, plus "OS-logo shift key"??? what this means?
