The application demo had a "Blue" and a "Bold" menuitem both with
the Ctrl-B accel. This is confusing, since only one of them works.
Change the accelerator for bold to Ctrl-Shift-B, so they both work.
<item>
<attribute name="label" translatable="yes">_Bold</attribute>
<attribute name="action">win.bold</attribute>
- <attribute name="accel"><Primary>b</attribute>
+ <attribute name="accel"><Primary><Shift>b</attribute>
</item>
</section>
</submenu>
