Reminders App in OS X Mountain Lion
Reminders is a brand-new Mac app available in OS X Mountain Lion that will be familiar to anyone with an iDevice because it bears more than a passing resemblance to the iOS Reminders app.
Reminders help you stay organized. Unlike an event, a Reminder item isn’t necessarily associated with a particular day or time (though it can be). Furthermore, Reminders can be location-based, which is handier on an iDevice than a Mac, but a great feature if you have such a device. Finally, Reminders can have a priority level of Low, Medium, High, or None.
If you have an iDevice and use iCloud, your Reminders will appear on all your Apple devices — other Macs, iPhones, iPads, and iPod touches — simultaneously, which means you should never miss a Reminder. Just set a Reminder on your Mac or any iDevice, and you’ll never forget anything.
Before you create or manage your own Reminders, there are a couple of things you should know, starting with the concept of Lists. Reminders includes a List called Reminders by default. You can delete or rename it if you like, and you can create additional Lists if you care to by choosing File→New List, pressing Command+L, or clicking the plus button at the bottom of the window.
When you check the box for an item, the item is moved from whichever List it’s on to the Completed List.
Here are more helpful techniques for working with Lists:
To rename a List: Right-click or Control-click the List, choose Rename from the contextual menu, type the new name, and press Return or Enter when you’re done. Or, select the list, press Return or Enter, type the new name, and then press Return or Enter again when you’re done.
To display a List in a separate window: Double-click the List’s name; right-click or Control-click the List and choose Open List in New Window from the contextual menu; choose Window→Open in New Window; or press Command+Return or Enter.
To show or hide the little calendar: Choose View→Show/Hide Calendar; press Command+Option+K; or click the little calendar button below the little calendar.
To show or hide the List sidebar: Choose View→Show/Hide Sidebar; press Command+Option+S; or click the little triangle in a button on the left beneath the little calendar.
You don’t have to have more than one List. You don’t even have to change the default List’s name from Reminders if you don’t want to. The point is that you can make a bunch of Lists or dump everything into a single List; just use Lists to organize your Reminders so they make sense to you.
