Tips & tricks

iPhone search: swipe down to find anything

Swiping down on the home screen opens search — apps, contacts, messages, and calculations. Faster than hunting for icons.

Bedtime mode: your phone goes to sleep before you do

An hour before bed, your phone dims, quiets down, and stops tempting you. Set it once — and sleep better every night.

Type by swiping: a third faster

Gliding your finger across the keyboard looks odd and works great. After a week you won't remember why you tapped.

Android: two apps on screen at the same time

Notes next to your browser, or a calendar next to email — split screen is genuinely usable on bigger phones.

Batched notifications: a summary instead of a drip

iOS and Android can both hold non-urgent notifications and deliver them as a summary at times you choose. Your phone stops yanking at your attention.

Hold the space bar: your keyboard turns into a trackpad

Landing a finger right in the middle of a word is a lottery. Holding the space bar turns your keyboard into a touchpad for precise cursor movement.

iPhone Shortcuts: your phone switches into work mode by itself

The Shortcuts app can do automations: arriving at the office turns on Do Not Disturb, opening Instagram starts a timer.

iPhone: tapping the back triggers anything

A double-tap on the back of your phone can launch the flashlight, a screenshot, or a shortcut. A hidden button hardly anyone knows about.

Voice typing in Google Docs

Ctrl+Shift+S

Word: heading styles instead of manual bold text

Heading 1 and Heading 2 aren't just about looks — they power the navigation pane, an automatic table of contents, and chapter collapsing.

The middle mouse button: opens and closes tabs too

Middle-clicking a link opens it in a new background tab. Middle-clicking a tab closes it — no need to hit the tiny X.

A floating video window over everything else

Picture-in-picture keeps a video (a call, a tutorial) in the corner of your screen while you work elsewhere.

Space scrolls one screen at a time

Shift+Space
