This option exists in Opera 12.18 and in Firefox. It does not exist in Opera 53, so I guess it is missing from Chrome too. That would explain why it does not yet exist in Vivaldi. It would have to be implemented by the Vivaldi Team.

@jane-n Thanks. Looking better now.

@rotfl If a request is not created, I create it directly through JIRA, not via the bug tracker 😜

Hello, I update my previous post as I find that S3 Donwload Manager it's finally available in Chrome Store. I already use 3 addons in Firefox form this dev and I love it. Of course S3 DM fits with the post, as it have the ability to delete downloaded files from system, with also some more useful options that automate steps. It could be a nice substitute while waiting for Vivaldi development improve download managment.

@pesala I'm trying to accomplish the delete without using the keyboard (otherwise I would just use the Delete key directly). Highlighting text with the mouse and then right-clicking normally brings up "Delete" as one of many options with most Windows applications (including other browsers, and apps as basic as Notepad and Windows Explorer - see image below for Explorer example), so it's something I've just been doing for many years. To me this just seems to be a common function, but as I mentioned in my opening post, I have a similar issue with OpenOffice (which is even more surprising, since one of its modules is a word processor). So that made me think that the right-click "Delete" option may be less common for operating systems other than Windows (otherwise, why not include it automatically in an application?). Well others have said that it's currently not built in to Vivaldi, so I'll probably post it as a feature request for future versions. Thanks to all who took the time to respond!
