St. Clair Software has released Default Folder X 4.6.8, adding compatibility for the public beta release of OS X 10.10 Yosemite. The update also improves the speed of the Rename command and fixes a bug when running in 10.9 Mavericks so you can use standard contextual menus instead of those provided by Default Folder X. ($34.95 new, $10 off for TidBITS members, free update, 10.6 MB, release notes, 10.6+)
Enter Dashboard, Expose, or Spaces Temporarily
Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.
