yes. Do you want me to run a command and send the output to you. I just broke 
at scorearea_keypress_event.

(gdb) p *widget
$9 = {object = {parent_instance = {g_type_instance = {g_class = 0x92940c8}, 
ref_count = 5, qdata = 0x9197200}, 
    flags = 2170816}, private_flags = 3584, state = 0 '\0', saved_state = 0 
'\0', name = 0x0, style = 0x9295808, 
  requisition = {width = 0, height = 0}, allocation = {x = 2, y = 129, width = 
1049, height = 527}, window = 0x92abe60, 
  parent = 0x918c728}
(gdb) p *event
$8 = {type = GDK_KEY_PRESS, window = 0x8fb7188, send_event = 0 '\0', time = 
52511768, state = 0, keyval = 99, length = 1, 
  string = 0x9280e68 "c", hardware_keycode = 54, group = 0 '\0', is_modifier = 
0}
