In a previous tip I discussed how to create a Mac sticky note from inside a Cocoa application, but I forgot to mention about how to use stickies as a standalone application.
Fortunately, it's pretty easy. Just open your Applications folder, and click the Stickies application icon. Once the Stickies application is started, just click File, and New Note to create a new sticky note, or press [Command][N].
Once you're started the Stickies application there are all kinds of crazy things you can do, including setting notes to float and/or be translucent, change fonts, sticky note color, and more.
Mac Stickies widget
If you're loving Mac Stickies on the desktop, you may also like the Mac Stickies widget. To check it out, just press [F12] to bring up your widgets. If it's not already displayed, look in the lower-left corner of the screen and click that big plus sign with a circle around it, as shown in the following image.
That will bring up something that looks like a dock for your widgets, as shown in the next figure.
The Stickies widget icon is probably not showing on this first screen of available widgets, so you may need to click the left or right arrows on the side of this dock to show the next page of widgets. When you see the Stickies icon click it to open this widget, and you're in business!
