You can easily do all that with alfred on mac. For example, I have a keyboard shortcut to open the current url in archive.is and the wayback archive for instance. Just a simple applescript to get the current url from chrome and then open up the two websites. Easier to manage than writing a browser extension or some kind of bookmarklet.

I have lots of custom searches accessed by a keyword, usually two letters, and I can modify the query string any way I want or take some other action with it. My 'lucky' searches use DDG to go straight to the top result on the site(wikipedia, mdn etc) but they also stuff the query into the system wide find pasteboard. If the top result isn't right I can immediately jump to a google search of the site with the search query with a keyboard shortcut.
