I rely upon the mini-application Alarms throughout the day as a reminder backup for my busy work week. And just as Alarms keeps me from forgetting last minute scheduled phone calls, Stefan Fürst's latest app, CheatSheet, is a memory enhancer (or crutch), providing keyboard shortcuts for any application at the touch of a long ⌘-Key hold. Very helpful, yet always hidden until you need it. Download it, launch it, love it.
