The usual way is to associate it with a label with mnemonic.
User can press Alt-key to switch to it then (Alt-B here):

    label = gtk_label_new_with_mnemonic("_Blah");
    ...
    gtk_label_set_mnemonic_widget(GTK_LABEL(label), widget);

It is possible to use some arbitrary keystroke too by adding
an accelerator (see GtkAccelGroup docs) and calling
gtk_widget_grab_focus(widget) on the target widget when it's
activated (mnemonic activation does gtk_widget_grab_focus()
only sometimes in fact, but it does it in the cases you are
interesed in).
