Tips & tricks

Paste Values Only: Formulas Out, Numbers Stay

Ctrl+Alt+V

Ctrl+Alt+V opens Paste Special — paste results without formulas, formats without content, or transpose a table.

Sum and Average Without a Formula: Just Select

Select the cells and look down at the status bar — the sum, average, and count are always right there.

Ctrl+PageDown

Move between the sheets of a workbook from the keyboard — no clicking the tabs at the bottom.

A PivotTable in Two Minutes

A revenue summary by month and category out of thousands of rows? Insert → PivotTable, then drag three fields.

Alt+=

Cursor below a column of numbers, Alt+equals — and SUM is done, range and all.

Data validation turns a cell into a menu of allowed values. Task statuses or categories can no longer be typed wrong.

Removing Duplicates in Three Clicks

Data → Remove Duplicates cleans up a list of contacts or line items — and tells you how many it deleted.

Ctrl+;

Ctrl+semicolon inserts today's date as a fixed value — unlike the TODAY() function, it doesn't change.

A New Line Inside a Cell: Alt+Enter

Alt+Enter

Freeze Panes: Keep Headers Visible Even at Row 500

View → Freeze Panes keeps the table header locked at the top no matter how far you scroll.

XLOOKUP: Lookups Without VLOOKUP's Weaknesses

The newer replacement for VLOOKUP searches in either direction, doesn't break when a column gets inserted, and has a built-in “not found” fallback.

Duplicate values, overdue deadlines, or below-average results highlight themselves — you just define the rule.

Flash Fill: Excel Finishes the Pattern for You

Ctrl+E

Ctrl+T

Ctrl+T turns a range into a “smart” table — automatic filters, formatting for new rows, and readable formulas.

Set your Teams status with a duration, not just a toggle

“Do not disturb until 12:00” tells coworkers more than a permanent red dot — and it turns itself off.

Shift+Enter

Enter sends a Teams message right away. Shift+Enter starts a new line, and the formatting button opens the full editor.

Excel: Ctrl+Arrow Keys Jump to the Edge of Your Data

Ctrl+↓

Don't scroll through a sheet with thousands of rows. Ctrl+arrow jumps to the end of the block, and with Shift it selects as it goes.

Filter your Teams activity down to just @mentions

The Activity feed can show only messages where someone mentioned you. Everything else is mostly noise.

Teams in meetings: mute and camera from the keyboard

Ctrl+Shift+M

Ctrl+Shift+M toggles your mic, Ctrl+Shift+O toggles your camera. When it's suddenly your turn to talk, you're not hunting for a button.

Teams: Ctrl+E to search, and jump anywhere from there

Ctrl+E

The search bar at the top finds people, messages, and files — and a slash launches commands.

The up arrow fixes your last message

↑

Typo in a message you just sent? Press the up arrow and you're editing right away — no hunting through menus.

Custom channel sections: important on top, noise below

Split your sidebar into sections — Projects, Team, Noise. Channels you don't need to see get collapsed.

Reply in threads, not in the channel

A threaded reply keeps a discussion together and doesn't flood the channel. A team that threads has half the noise.

Saved items: bookmarks for Slack

The bookmark icon on a message adds it to Later — your personal list of things to come back to.

Set working hours for notifications in Slack

A notification schedule automatically quiets Slack outside working hours. It leaves you alone in the evening — and shows colleagues when you're reachable.

Slack search: from:, in:, before:

Operators narrow a search to a specific person, channel, and time period — instead of scrolling through history.

Remind yourself about a message when you'll have time for it

“Remind me about this” brings a message back at a time you choose. Slack stops being the place where tasks get lost.
