Inspect element instantly as in chromium with Ctr + shift + C
Its great to see the enhancement in the latest vivaldi versions, One thing I really love about chromium based browsers is the handy CTR+Shift+C shortcut launching the inspector while selecting the currently hovered item in the DOM. For a web developer once you get used to this shortcut its indispensible. Basically this is the only reason I still don't use Vivaldi as my default browser. But maybe i just missed some trick
Try ctrl+shift+I; if you don't like that combo, go to settings->keyboard->scroll down to developer tools and add the keyboard shortcut that you want….
Hope that helped~
