Need to check something in another email message while composing a message in Mail on an iPhone? Many people don’t realize that you can swipe down on the top of the draft to dock it at the bottom of the screen, look something up in another message, and then expand the draft again by tapping it at the bottom of the screen.
It’s helpful to unplug occasionally and ignore email while on vacation or otherwise away from your work routine. And it’s a good idea to set up a vacation auto-responder to tell correspondents what to do in your absence. It might be tempting to create such an auto-reply with a rule in Mail on the Mac, but resist the temptation! It’s way too easy to end up sending replies to every message from a mailing list or to addresses that will themselves reply back, causing a mail loop where each message generates another reply, ad infinitum. Instead, always set up such auto-responders in the server settings for your email provider, which are better about avoiding mail loops. Here are instructions for Gmail, iCloud, Outlook.com, Spectrum, Xfinity/Comcast, and Yahoo. If you use a different email provider, the instructions will likely be similar; check with your provider for details.
Every now and then, we’ve seen (wedged) iPhones stop being able to access the Internet, either via Wi-Fi or a cellular data connection. Assuming that the Internet connection is working for other devices, there are two easy ways to reset your iPhone’s connection and get it working again. First, enable Airplane mode to shut off the iPhone’s radios—bring up Control Center and tap the Airplane mode button. After a few seconds, tap the button again to turn it off. Second, if toggling Airplane mode doesn’t work, power down the iPhone by pressing and holding the top or side button (iPhone 8 or earlier) or both the side button and a volume button (iPhone X or later) until the slider appears (or go to Settings > General > Shut Down). Drag the slider to turn off the iPhone. Once the phone is powered down, hold the side (or top) button again until the Apple logo appears. In just a moment, your phone will be back on, and you should be able to access the Internet normally.
Here is a trick for enabling caps lock when typing in iOS. The Caps Lock key on Mac keyboards often feels extraneous, since it’s easy enough to hold the Shift key while typing multiple capital letters for acronyms like HIPPA or when you want to shout GET OFF MY LAWN! But if you need to do that on an iPhone or iPad, it’s annoying to keep tapping the Shift key to switch to the uppercase keyboard for each letter. Luckily, Apple has baked a time-saving trick into its onscreen keyboard. Tap the Shift key twice in a row to lock it on, type the letters you need, and tap it again to unlock it. Notice that when Shift is locked on, a horizontal line appears beneath the arrow on the Shift key.
Siri on the Mac hasn’t been as useful as on iOS devices, but with macOS 10.14 Mojave, Apple enhanced the Mac version of Siri in a variety of ways. Apple says that Siri now knows about food, celebrities, and motorsports, but more interesting is how you can ask Siri to control your HomeKit devices (“Turn on the bedroom lights.”) and locate your iOS devices or AirPods via Find My iPhone (“Where is my iPhone?”).
