Haven't any of you people heard of triple-clicking? Single click places the cursor, double click selects a word, and in some interfaces (including SC.com) a triple-click selects the whole text field.
I think that "click-click-click-Delete, click-click-click-Delete, click-click-click-Delete, click-click-click-Delete" would take considerably less time than programming an image-only panel cloning. It takes me about four or five seconds.
Other useful keyboard shortcuts you guys may find helpful are the old faithful Ctrl+C, Ctrl+X, and Ctrl+V, copy, cut, and paste. If you get to the third panel and realise that you've fucked up the comic timing, so your speech balloons need rearranging, you can triple-click to select a whole balloon, Ctrl+X to cut the text out of the balloon, and Ctrl+V to paste that text into a different balloon. Keep one balloon empty and you can do a Towers of Hanoi thing, shuffling the speech balloons about without having to retype another word.
