I know how to set a custom font to the action bar. I just have to extend SherlockFragmentActivity and override setTitle like this: 

```
@Override
public void setTitle(CharSequence title) {
    String str = String.valueOf(title);
    str = str.toUpperCase(Locale.getDefault());
    SpannableString s = new SpannableString(str);
    MetricAffectingSpan span = new MetricAffectingSpan() {
        @Override
        public void updateMeasureState(TextPaint p) {
            p.setTypeface(FontManager.INSTANCE.getAppFont());
        }

        @Override
        public void updateDrawState(TextPaint tp) {
            tp.setTypeface(FontManager.INSTANCE.getAppFont());
        }
    };

    s.setSpan(span, 0, s.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

    getSupportActionBar().setTitle(s);
}

```

However, things get complicated with a contextual action bar. The library uses a factory to return the contextual action bar, like this:

```
ActionMode mode = getSherlockActivity().startActionMode(mActionModeCallback);
mode.setTitle("whatever");

```

I COULD override ActionMode, yet the lib won't return it.

Any ideas?
