what exactly is the default web clipper screenshot shortcut? I'm using latest Firefox, latest Evernote desktop (PC) and latest webclipper add-on. The only reason I have installed this is to get captures of USPS.com's Click N Ship invoices for tax purposes (they don't have an export function, maddeningly -- I have other options now (stamps dot com, shipworks), but capturing 2012's records are cumbersome). At the moment I am having to leave the keyboard to click the webclipper button for every invoice, and there are hundreds. What do I do??
