static gboolean	_slideshow_start_stop_accel (GtkAccelGroup accel_group, GObject accelerable, guint keyval, GdkModifierType mods, gpointer user_data)
	Toggle slideshow auto-advance using the same stepping code path as manual navigation, so pause/resume stays consistent with the current buffer state.

static gboolean	_slideshow_slow_down_accel (GtkAccelGroup accel_group, GObject accelerable, guint keyval, GdkModifierType mods, gpointer user_data)
	Increase the slideshow delay and store it immediately so repeated keyboard adjustments persist across view changes.

static gboolean	_slideshow_speed_up_accel (GtkAccelGroup accel_group, GObject accelerable, guint keyval, GdkModifierType mods, gpointer user_data)
	Decrease the slideshow delay and store it immediately so the current playback cadence matches the persisted preference.

static gboolean	_slideshow_step_forward_accel (GtkAccelGroup accel_group, GObject accelerable, guint keyval, GdkModifierType mods, gpointer user_data)
	Advance the slideshow while keeping auto-advance and global actions synced with the image currently displayed fullscreen.

static gboolean	_slideshow_step_back_accel (GtkAccelGroup accel_group, GObject accelerable, guint keyval, GdkModifierType mods, gpointer user_data)
	Step back in slideshow mode and keep the fullscreen image as the sole active image when the selection is temporarily cleared.
