Stairways Software has released an update that fine-tunes its popular macro utility Keyboard Maestro. In version 4.2, pressing the Option key enables you to edit macros chosen from the Status menu or floating palettes, a palette of macros displays when a duplicate hotkey is pressed, a new action can execute other macros, and certain macros can be canceled by neglecting their required actions. Also, typed string triggers can now contain Return characters, AppleScript error logging is available, regular helpful program tips can be received via email, and MIDI triggers and MIDI actions are available for Note On, Note Off, and Control Change. Finally, several bugs have been fixed, including a sorting issue with the macro list and a crashing bug in the Select Menu Item action editor. ($36 new, free update, 9 MB)
