You shouldn't have to perform 26 10 clicks and keyboard actions before you get them. 27 28 With this script installed in GreaseMonkey, you can just ... 29 - search in Google for your conference paper 30 - click on the ACM/Springer/IEEE link 31 - Once you see the monkey icon (yes, that's right) your PDF is ready to 32 download. 33 34 * Adding Your Own Site: 35 36 { 37 url_snip: "if this variable
