Pushing to get one last significant update in before Apple restricts the Mac App Store to apps that can be sandboxed, Stairways Software has released Keyboard Maestro 5.3 with a number of image manipulation and mouse click actions added to the powerful automation utility. On the image front, Keyboard Maestro 5.3 now enables you to create new images; flip, rotate, resize, and crop images; create images out of composites of images, styled text, and shapes; find an image on your screen; and capture one or all screens or a selected window. Enhanced mouse click actions include support for double and triple clicks, dragging with any button, and clicking relative to the center of a window, screen, or image. You can also now type the word APPLICATION (in all caps) within menu selections as an alias for the current application. Other additions include a new Highlight Location action and live reporting of condition test results in action editors. A number of tweaky bug fixes round out the update. ($36 new, free update, $25 upgrade from versions previous to 5.0, 17.5 MB, release notes)
Extract Directly from Time Machine
Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.
You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.
As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.
Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.
