This creates a label with the 's' underlined.  The second call says that 
when alt+s is pressed, the entry widget should be activated.

AccelLabels are mainly used in menus.  They display a label (like a 
normal GtkLabel) plus a key combination on the right.  The second call 
here says to watch accelerators on the entry widget.  So if you assign 
ctrl+; to the activate signal of the entry, then that key combination 
will be displayed in the accel label beside the text "_something" (note 
that the s is not underlined).

Note that the second call doesn't have anything to do with accelerators 
on the label itself (activating a label isn't very interesting anyway).

The AccelLabel will watch for changes in the accelerators as well.  This 
is mainly visible when dynamically changing accels.
