I took Hitchhiker’s Sogudi shortcut and modified it to use a JavaScript-prompt() to ask for the tags. Use it in Safari as the first bookmark or so and activate it by pressing ?+1 (or other number depend on where on the bookmark bar it is)

Installation:

  1. Drag this link to your Bookmark bar: + del.icio.us
  2. Right click on the bookmark and choose “Edit Address
  3. Change CHANGEME to your del.icio.us username
  4. Done
