It's the one I use, too. But you don't need to navigate menus: if you open the settings, you can bind the ROT13 switch to a keypress.
I tried that, but I couldn't figure out what kind of input it wanted to set the keyboard command. It wasn't in a standard symbology when I managed to get something typed in, and didn't respond normally to me typing the key sequence I wanted. Can you tell me how to make it work?
Every time I come across one, it annoys me. I have to copy the text, open a new tab to the ROT13 site, paste the text, and click the translate button.
Compare this to something like a collapsable spoiler button-box where you press a button and it expands and expands a box with the appropriate text underneath it. Even making a [spoiler][/spoiler] tag that gave a black background and equally black text would be better than the current ROT13 solution.
Was there actually a reason for doing things this way? If so, why not just include the ROT13 translation in the javascript that'd open and close the textbox? Comments? Criticism?
