This looks useful… I’m always forgetting keyboard shortcuts that would save me time.
As amazing as it may seem, until now the Dashboard has been missing a key utility that will be especially welcome by recent Windows or Linux switchers as well as other newcomers to Mac OS X. xCuts finally puts a full reference of Mac OS X Keyboard Shortcuts at your fingertips in the Dashboard.
This widget is powered by an external MySQL database that will be updated periodically with new information, allowing you to easily browse or search its contents. The xCuts are organized by Category, Scope, and Object, and you can even drill down to a second cross-referenced level if you need to. Or just use the fast live search form!
xCuts includes tips on the use of certain shortcuts, and it’s designed to let you copy and paste shortcuts to external documents. This resizable widget uses Ajax and the terrific Script.aculo.us (http://script.aculo.us) effects library to work its visual magic. When you’re done, click the title to compact xCuts down to a tiny lozenge for later use.
