Pressing Alt/Shift+Enter on a result should open a browser window with result page from default Search Engine configured through Web Shortcuts in System Settings.
Alt+Enter would be preferred instead of Shift+Enter as that shortcut is going to be assigned to another feature I requested and the concerned developer made a patch here: https://phabricator.kde.org/D3971
I would prefer, that the result is copied to the clipboard. This is more flexible, websearching the result is just one of the things you can do after the text is in the clipboard. For example, if you want to do a search with a specific webshortcut, you can then enter the webshortcut and ctrl + v.
What do you mean by result exactly? The resulting link with the searchengine and query? >Pressing Alt/Shift+Enter on a result should open a browser window > with result page from default Search Engine > configured through Web Shortcuts in System Settings. Well the concept is that you have to specify a search engine and adding an action to ignore the specified search engine seems a bit off :/. If you dislike this you might want to check out an extra KRunner plugin: https://github.com/alex1701c/QuickWebShortcuts > I would prefer, that the result is copied to the clipboard. Again question what the result should be, but this seems easy to implement. And just for context: BUG 390009 would be the default action which would be triggered with Shift+Return.
