I just got my iPad for Christmas and am finding out new things every day. I just wanted to post this in case someone was wondering how to use accents and diacritically marked letters while typing on iPad, such as ü, é, ñ and all sorts of other ones. I stumbled onto this by accident, but all you have to do when using the keypad is to hold down the letter until a window pops up where there are alternate letters and just click on the letter you would rather have! So, just hold the letter slightly longer than normal and the window will pop open. It is FANTASTIC!!!
