add a key press/release event handler for the window.
switch (ev->keyval) {
case GDK_KEY_foo:
do_something ();
break;
....
be careful about deciding whether you want to drive actions on press or release.
for better overall app design, make all "do_something()" methods into
GtkActions, and then
switch (ev->keyval) {
case GDK_KEY_foo:
action = get_action ("do_something");
action->activate ();
(the implementation of "get_action" is left as an exercise for the reader)
this then allows you to set up GUI elements like buttons as proxies
for the action, and then your entire GUI is nice and consistent.
