Ctrl+D
Duplicate an object, move it into place — and the next Ctrl+D copies with the same offset built in. A row of evenly spaced elements in seconds.
Need to send three pages out of a fifty-page PDF? Print the range “12-14” to PDF and the new file is born. No installing anything.
Highlighting and annotating a PDF is handled by the free Acrobat Reader, Edge, and Preview on Mac. Feedback belongs in the file, not in a five-paragraph email.
Type @name in the body of an email — Outlook adds the person to the recipients automatically and highlights that something's expected of them. No more overlooked tasks buried in the CC line.
Word, Excel, and PowerPoint quietly save copies of your work as you go. File → Info → Manage Document recovers even files you never saved.
Most people sit in their chair exactly as it arrived from the store. Three checkpoints — elbows at desk height, knees at a right angle, feet on the floor — take a minute to fix.

Default pointer and scroll-wheel speed is tuned for monitors from a decade ago. Two sliders save hundreds of arm movements a day.
A laptop sitting on the desk shoots your chin and the ceiling from below, and a window behind you turns you into a silhouette. Camera height and light direction fix more than a new webcam ever will.
One checkbox in your calendar shortens default meetings to 25 and 50 minutes. Between calls you get a breather you don't have today.
Don't arrange a meeting time over email. Google Calendar and Outlook lay attendees' calendars side by side, and you spot the open slot at a glance.
Google Calendar and Outlook can both show a second time axis next to your own. Plan a meeting across time zones by looking, not by doing math in your head.
Ctrl+click on sheet tabs groups them — and whatever you type into one gets written into all of them. Fix twelve monthly sheets in one move.
Switching back and forth between the sheet with source data and the sheet with results? View → New Window shows both at once.
Alt+;
Copying a table with hidden rows and they paste in too? Alt+; selects only the visible cells — the hidden ones stay home.
“You froze” usually doesn't mean slow internet — it means unstable Wi-Fi. An Ethernet cable is the single most reliable upgrade for calls.
Put the meeting window on the monitor with the camera, notes and materials on the other. You look people in the eye, never share anything private, and minutes write themselves.

An explainer with prompts: what it means to let AI run in a loop, what's true in the hype, what's overblown, and how to safely try your first loop.

A complete guide with prompts: Beeper unifies WhatsApp, Messenger, and Slack into one app, and Claude pulls promises and deadlines out of them via MCP on a regular schedule and writes them into Notion. Includes a patient introduction to the terminal for anyone who's never opened one.
Gaps in your prompt get silently filled with the model's own assumptions. Have them listed out — see what the answer is standing on before you build work on top of it.
Claude, ChatGPT, and Gemini can all edit a message you've already sent and answer again from a clean slate. A lesser-known button that rescues tangled conversations.
Copying a table out of a PDF turns the columns into one tangled noodle of text. Upload the PDF to AI, ask for CSV — and check the control total.
New project, and a document full of acronyms and jargon? AI pulls out every term and explains it in context — flagging what it's only guessing.
A forwarded conversation, “see below,” and thirty emails of history. Drop the thread into AI and ask: who's claiming what, where's the agreement, and what are you supposed to do.
Attendance against sign-ups, payments against orders: paste two lists and AI lists what's in one and missing from the other — even through typos.
Before you present, have AI generate the audience's questions — curious, skeptical, and the one from your boss about money. You'll find out which ones you can't answer while there's still time.
In Czech, “Dear Mr. Novák” is wrong — it has to be “Dear Mr. Nováku,” the vocative case. AI adds a properly-declined salutation column to your contact table, for hundreds of names at once.
Tell AI the app, version, and what you're looking for — you get the exact path in the settings. No more clicking blind or following guides written for a five-year-old version.
An email typed on the wrong keyboard layout or an export from an old system: paste the text into AI and get it back with the accents in the right place. It works in reverse too.
Instead of trawling ten-year-old forum threads, paste the error message — or a screenshot of it — into AI and ask three things: what it means, what to do, and what not to do.
Every PDF opens in Edge even though you read PDFs elsewhere. Photos open in an app you never chose. Two minutes in Settings → Default apps and files start opening where you actually want them.
