There probably be a signal of the widget to emit when the
key is pressed in place of "F1", e.g. "clicked".  I'm not
sure about the C++ arguments, so here's C:

gtk_widget_add_accelerator(button,      /* widget */
                           "clicked",   /* signal */
                           accel_group, /* accel_group */
                           GDK_F1,      /* key */
                           GDK_RELEASE_MASK,  /* accel_mods */
                           0);          /* accel_flags */

You may put some particular flags there instead of 0, but
using GTK_ACCEL_MASK is not a good idea, as it has ALL the
flags set.
