Both Safari on the Mac and the iOS version have a way to jump back multiple steps in your Web browsing, without you having to pound on your back button. In this tip, Melissa Holt's going to explain how it works. Punch and pie won't be served within, but you may learn something, which is at least 10 percent as good as punch and pie.

Did you know that you can expand an entire folder, including all of its subfolders, with one simple trick in the Finder? Well, you can. It's easy, and it's fun. Well, as fun as anything in the Finder can be, we suppose. 

In iTunes 11, Up Next will let you decide exactly what you want to listen to and when, without you having to create a custom playlist just because you're in the mood for some Beatles followed by Pink Floyd. It sounds simple, but there's a lot to understand about how it works and how to use it to your best advantage. Here's the rundown.

Apple's Calculator app, included in OS X, is a handy tool for performing both quick and advanced calculations. To help keep track of multiple calculations, Apple includes a paper tape feature that logs past entries and solutions. We'll show you how to use this small, but incredibly useful feature.

iTunes 11 has a neat new feature called Preview History, which lets you backtrack to find songs, movies, or TV shows you watched previews of. Step One: Learn how to use it. Step Two: Learn how to clear it, since your history will sync to your other devices through iCloud. No fair making us more aware of our crappy taste in music, Apple.

A long history exists in the computing world of hiding "easter eggs," cool little tidbits that are there more for the programmer's indulgence than the actual user, and OS X (indeed, most software Apple has ever produced) has its share of them. Today we find one that traces back to OS X's Unix roots (specificall FreeBSD), and is quite important... if you're a chosen hobbit.

Before you hand your Mac to someone or do anything else that would involve others seeing your screen, it might be wise to temporarily disable your Notification Center alerts and banners. You know, so, ahem, those people won't, um, see anything they (cough) shouldn't. Anyway, here's how you do it, not that we're suggesting you've got stuff to hide or anything.

Annoyed with bad Wi-Fi and Bluetooth performance on your Retina MacBook Pro? That fancy new USB 3.0 hard drive you connected may be the problem.

Depending on how your iOS device is set up, you may see a banner notification come down from the top of your screen every time you get an email, a text message, or a Twitter mention. This can be frustrating if you happen to be doing something that gets covered up under those notifications, so here's how you tell them to scram, pronto.

If you've ever used System Preferences' Installed Software list to troubleshoot installation problems, you may be disturbed to find out that it's gone in Mountain Lion. OK, not gone. Moved. But moved to an extremely out-of-the-way location. And while that handy list isn't bothering anyone where it's living now, it's sure not going to help if no one knows where it is, either. Oh, Apple. You and your changes.
