Chrome extension. For the lazy graders.
##Usage
Clone the repository into a directory. Then, in Chrome, go to chrome://extensions, select "Load unpacked extension", then choose the directory you cloned to.
Whenever you're in a textarea (e.g. Github issue tracker comment), press ctrl + opt + i (ctrl + alt + i in non-Macs), and select one of the canned responses from the popup by pressing the corresponding number. Then, iterate through the placeholders with ctrl + opt + j / k (ctrl + alt + j / k in non-Macs).
Right now this extension is quite raw, and all configs are done manually. All the canned responses are located under script.js, inside the array of objects called cans. To add/remove/edit any of the entries, modify that array, and press "reload" under the Chrome extensions page.
