-- signal Completion::move-page
{- |
The 'GI.GtkSource.Objects.Completion.Completion'::@/move-page/@ signal is a keybinding
signal which gets emitted when the user initiates a page
movement (i.e. switches between provider pages).

\<keycombo>\<keycap>Control\<\/keycap>\<keycap>Left\<\/keycap>\<\/keycombo>
is for going to the previous provider.
\<keycombo>\<keycap>Control\<\/keycap>\<keycap>Right\<\/keycap>\<\/keycombo>
is for going to the next provider.
\<keycombo>\<keycap>Control\<\/keycap>\<keycap>Home\<\/keycap>\<\/keycombo>
is for displaying all the providers.
\<keycombo>\<keycap>Control\<\/keycap>\<keycap>End\<\/keycap>\<\/keycombo>
is for going to the last provider.

When /@step@/ is equal to @/GTK_SCROLL_PAGES/@, the page size is defined by
the 'GI.GtkSource.Objects.Completion.Completion':@/provider-page-size/@ property.

Applications should not connect to it, but may emit it with
@/g_signal_emit_by_name()/@ if they need to control the page selection
programmatically.

Starts a new completion with the specified 'GI.GtkSource.Objects.CompletionContext.CompletionContext' and
a list of potential candidate providers for completion.

It can be convenient for showing a completion on-the-fly, without the need to
add or remove providers to the 'GI.GtkSource.Objects.Completion.Completion'.

Another solution is to add providers with
'GI.GtkSource.Objects.Completion.completionAddProvider', and implement
'GI.GtkSource.Interfaces.CompletionProvider.completionProviderMatch' for each provider.
