If you want faster text entry within e-mails on your iPhone/Touch, TapIt4Me may be just what you need. This inexpensive app lets you create shortcuts that it expands into text. For example, you can set it up so that typing syl will expand into See you later.
Right now it only works within e-mail. If you want to reply to an email, then
click reply in Apple’s Mail app then press the home button and launch TapIt4Me. When your reply is ready, select Mail from the action menu: your reply will appear right where it should go in Apple’s Mail app ready for you to tap Send.
Simple, eh? I also tried composing an email with it, using a similar procedure. It worked, but it also copied my short test text into the Subject Heading as well as into the body of the text. I don’t know if that is a bug, or if I did something wrong.
Anyway, it’s very cool. And, if you use TextExpander on your iMac, like I do, you can import its shortcuts into TapIt4Me. The company’s website also says there is a Microsoft Word macro available to convert your Word autotext/autocorrect entries for use within TapIt4Me.
I wish it worked within Safari and other apps that have a text interface, but at least it works for email.
