Keyboard shortcuts are precious when using the shell. I've listed some of my favorites, but this list is incomplete (to say the least). If you have already mastered the shortcuts that I've listed, then the next step is to read: man bashThe man[ual] page for the bash shell doesn't specify the ' alt' or ' option' key, it instead refers to ' mod' or modifier key. This article describes the modifier key behavior for Macs. Linux and Windows uses the 'alt' key in most cases. Also, note that the man page for bash refers to ' rubout'; this is the ' <-- Backspace' key for PC-based systems and ' delete' on Macs.

Screen Capture iPhone iPod Touch |
 |
 |
 |
|
 Call me slow, but I just learned how to take a screen shot of my iPod Touch. It works on the iPhone as well.
1. Press and hold the Home button.
2. Press and release the sleep/wake button.
The screen will flash to let you know it took the picture. Your screen shot will land in the pictures widget.

This list is far from complete, but should address the frequently used characters that are otherwise difficult when coding HTML.
