I use Firefox, where / is 'search in page' just like unix tools. I flop around like a dying fish when I have to use Chrome, where you have to use the gasp chorded keys ctrl+f.

A lifelong unixy sysadmin friend of mine particularly hates browsers and ctrl-w. To him, 'ctrl-w' means 'clear text field', particularly useful for things like password prompts where you can't see what's been written. So he goes to clear a password field in a browser window... and the webpage disappears
