Lemkesoft has released GraphicConverter 9.1 with a number of new and updated features. The venerable graphic conversion and editing utility adds the capability to attach images to email via a new menu item, anti-aliasing to the pen tool, the capability to extract images from a PDF, curve support for grayscale images, and pressure support for the pen tool. The user interface also receives a number of changes, including the addition of options to display a larger color label and color mode of an image in the browser, new Browse Copy and Browse Google Drive menu items, and added Save, Undo, and Redo icons to the toolbox. The update also improves animated GIF support (with more consistent transparency on import and export), improves rename options for extensions, and fixes a possible bug with selections and core image filters. ($39.95 new from the Lemkesoft Web site or from the Mac App Store, 222 MB, release notes).
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
