Uncomplex has released Mailplane 3.0.1, a maintenance release to the Gmail-specific mail client that revises keyboard shortcuts for opening mail due to a change that enables shortcuts to work in reply mode. The previous Mail > Open option has been revised to Mail > Open Conversation (Command-]), while Mail > Open In New Window has been added (Command-O). The update also lets you hide the tab bar, fixes an AppleScript issue with paragraphs in the mail body, squashes a bug with downloaded attachments containing special characters in their file names, and ensures that opening a file dialog no longer crashes the app in Mac OS X 10.7 Lion.

Type an em-dash on an iPhone
Typography and punctuation geeks rejoice! It's easy to type an em-dash on the iPhone's or iPod touch's virtual keyboard. To do so, tap the .?123 key to switch to the numeric keypad. Then touch and hold on the Hyphen key to reveal a pop-up strip showing an em-dash. Slide to the em-dash and release your finger.
Note that this basic trick works with many other keys on the virtual keyboard.
