Re: [orion-dev] CodeEdit - listen to CTRL+DOWN-ARROW
Hi Libing,
I tried this code, but it did not trigger when CTRL+ARROW-DOWN is typed. Could you please try and let me know if there is anything else need to be set for it to work.

Also, I found the below doc-ref from orionhub for the list of action-ids.  
https://orionhub.org/jsdoc/symbols/orion.editor.TextView.html#getActions

Assuming they are same for codeEdit, it may save you some effort to put that together.


Thanks

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
