Instead of sketching with your finger, it is possible to use a pen-like device called a stylus. To use a stylus with your iPad, iPhone, or iPod touch, you’ll need a special kind of stylus: a “capacitive stylus”.
One example is from Griffin Technology. Purchase Mental Note or Mental Note for iPad in October and receive 20% off a Griffin Stylus! (This offer is also valid for all existing customers.)
There are a couple of neat features Apple included related to entering text on your iPad, iPhone, or iPod touch.
Looking to position text? We don’t yet support automatic text positioning, but there is a (fun) workaround. Tap with multiple fingers on the space bar.The number of fingers used to tap the space bar will cause that many number of spaces to be inserted at the current cursor position. Tap with 2 fingers and 2 spaces are inserted. Tap with 3 fingers and 3 spaces are inserted. If you can fit 4 fingers on the space bar – yep, 4 spaces are inserted. iPhone & iPod touch users will want to try this in landscape mode.
Want to undo the last thing you just typed? Shake the device. This will only work while the keyboard is visible. A dialog will slide onto the screen and ask you to confirm the undo operation. Repeating the shake action allows you to redo the operation.
There have been some reports of unreadable characters in PDF files viewed on Windows machines. If you’ve used the Email as PDF option and the resulting PDF has unreadable characters in it, please try viewing the PDF using the Foxit PDF Reader. Unfortunately this may not solve the issue for everyone.
The fonts installed on Apple devices are not freely available on all systems, (Mac OS has support/licensing for all the fonts, and that’s why this issue is not seen when viewing the PDFs on Mac OS). Because of this, the fonts can’t simply be embedded into the PDF. Instead, the PDF reader software must try to substitute a font with some other font that it knows about if it can’t locate the document’s original font(s). The Foxit PDF Reader seems to do a good job of locating substitute fonts.
We are investigating an alternative way to generate the PDF files for a future release. For the time being though, if you find another PDF reader that fixes the issue for you, or you find a substitute font that fixes your issue, please let us know about it at firstname.lastname@example.org.
