ii. no option key, so i can't type a ç with a cedilla or pi π
I saw this in
iPademonium (continued), iPhone OS 4 (Small Dog's Tech Tails this week), under
Tip of the Week: Special Characters on iPhone OS (including iPad):
[...] the ability to type accent marks with the on-screen keyboard. This feature is part of the keyboard, not a particular app, so it can be used with Mail, Notes or even Pages.
To type a letter with an accent, simply hold your finger down on the letter for a second or two, and a number of options will appear. While still holding down your finger, just slide to the accented letter you want and release.
He doesn't mention Safari, and not having an iPad I can't test (this might be the "special tool we select via menu" you noted for Pages), but figured it was worth mentioning JIC it's useful.
