You pick up the local Indian restaurant menu and instead of just glancing down it to find the thing you want, you look along the top left corner for the 'Edit' button to then do a 'Find on this page' search... and not finding that you try and do CTRL+F...
And it takes you ten seconds to realise what you're doing and that it can't be done....
In my defence I'm dosed the eyeballs on painkillers and antibiotics...
