There's no way to leave a GtkComboBoxText field using the keyboard if it has the can_focus property enabled
Steps to reproduce
- Open any GTK+ dialog that has a combo box
- Use arrow keys or tab/shift+tab to navigate between fields, focus the combo box field
- Try to use arrow keys or tab/shift+tab to navigate between fields
The combo box remains selected; up/down arrors change the selection, left/right arrows do nothing, tab/shift+tab do nothing
I can use tab/shift+tab to continue navigating between fields.
