The ::show-completion signal is a key binding signal which gets
emitted when the user requests a completion, by pressing
Control+space.
This will create a GtkSourceCompletionContext with the activation
type as GTK_SOURCE_COMPLETION_ACTIVATION_USER_REQUESTED.
Applications should not connect to it, but may emit it with
g_signal_emit_by_name() if they need to activate the completion by
another means, for example with another key binding or a menu entry.
