Re: [orion-dev] CodeEdit - listen to CTRL+DOWN-ARROW

["Libing Wang" <Libing_Wang@xxxxxxxxxx>]

Generally speaking, you can always register
a orion.edit.command service(https://wiki.eclipse.org/Orion/Documentation/Developer_Guide/Plugging_into_the_editor#orion.edit.command)
with a keybinding to achieve your custom command, as I mentioned in the
https://wiki.eclipse.org/Orion/How_Tos/Code_Edit#The_codeEdit.serviceRegistry_instance.

There are exceptions, editorViewer.editor.getTextView()
instance, which is the core part of the widget, already preserved a lot
of "common sense" key bindings for actions like editor navigations,
etc. And ctrl+down-arrow & ctrl+up-arrow are two of them.
But do not worry, you can still use
some low level APIs to override these actions. Please refer to the following
snippet.

editorViewer.editor.getTextView().setAction("scrollLineDown",
function(){// use "scrollLineUp" for ctrl+up-arrow.
    console.log("my
action invoked!");
    return true;
});

Note that "return true" means
you do not want the default behavior at all, while "return false"
means you want both.

There are a lot of other preserved key
bindings. I have not yet documented it but will soon. I am working on an
html snippet so that you can run it to render a page listing up  all
the preserved actions with action id and associated key bindings. Then
from that list, the end users will have to decide if the desired key binding
collides with the preserved one. They have to grab the action id(e.g. "scrollLineUp")
and use the setAction API to override it.

Stay tuned on this incoming wiki section.

Hello,
Could you please tell me how to listen
to CTRL+DOWN-ARROW and CTRL+UP-ARROW?

Thanks
