Keyboard and productivity shortcuts

Why it matters

Technical work involves a lot of moving text around: copying an error message into a search, pasting a value into a spreadsheet, finding one word in a long log file, switching between documentation and your editor. Doing each of these with the mouse takes a few seconds. Doing them with the keyboard takes a fraction of a second, and it adds up to hours over a month. Shortcuts also keep your focus on the task instead of hunting through menus.

The core idea: one modifier key, many apps

Most shortcuts are a modifier key held down plus a letter. On Windows and Linux the main modifier is Ctrl. On macOS it is Cmd (the command key). Most shortcuts are the same letter on every system, so learning them once pays off in browsers, editors, spreadsheets and email.

In this lesson, Ctrl/Cmd + C means Ctrl + C on Windows/Linux and Cmd + C on a Mac.

The ten core shortcuts

Three more that are worth learning next:

• Ctrl/Cmd + Shift + T reopens the browser tab you just closed.
• Ctrl/Cmd + L jumps to the address bar so you can type a URL or search.
• Screenshot of part of the screen: Windows + Shift + S on Windows, Cmd + Shift + 4 on a Mac.

Text editing without the mouse

These work in nearly every text box, document and code editor:

• Arrow keys move one character or line.
• Ctrl + arrow (Windows/Linux) or Option + arrow (Mac) jumps a whole word.
• Home / End (Windows/Linux) or Cmd + left/right arrow (Mac) jumps to the start or end of the line.
• Add Shift to any of these to select as you move. For example, Ctrl + Shift + right arrow selects one word at a time.

Worked example: reporting an error

A script fails and shows a long error. You want to search for it and paste it into a message to your team lead.

1. Click into the error output, press Ctrl/Cmd + A to select it (or Shift + arrows to select just the last line).
2. Ctrl/Cmd + C to copy.
3. Ctrl/Cmd + T for a new tab, then Ctrl/Cmd + V and Enter to search for it.
4. Alt/Cmd + Tab back to your chat app, Ctrl/Cmd + V to paste.
5. Made a mess of the message? Ctrl/Cmd + Z.

That whole sequence takes about five seconds once the keys are in your fingers.

Finding the shortcuts in any app

You do not need to memorise every shortcut in every program. Two habits help:

• Read the menus. Most menu items show their shortcut on the right. When you use a menu item twice, note its shortcut.
• Look for the shortcut list. Many apps show one with Ctrl/Cmd + / (for example Google Docs and many web apps) or ? (Gmail, GitHub). Code editors such as VS Code have a command palette (Ctrl/Cmd + Shift + P) that shows shortcuts next to each command.

Touch typing

Shortcuts are faster still if you can type without looking at the keyboard. Touch typing means resting your fingers on the home row (ASDF and JKL;, with small bumps on F and J) and letting each finger cover its own keys. Free practice sites exist; ten minutes a day for a few weeks makes a noticeable difference. Accuracy first, then speed.

Common mistakes

• Pasting formatting you did not want. Ctrl/Cmd + Shift + V pastes as plain text in many apps (on a Mac some apps use Cmd + Option + Shift + V).
• Cut instead of copy. If you cut and then copy something else before pasting, the first item is gone. Prefer copy, then delete.
• Forgetting to save. Desktop apps often do not autosave. Press Ctrl/Cmd + S whenever you pause.
• Closing the wrong tab. Ctrl/Cmd + Shift + T brings it back.

Quick recap

• Ctrl (Windows/Linux) and Cmd (Mac) plus a letter covers most shortcuts.
• Copy, cut, paste, undo, redo, select all, find, save, tabs and app switching are the core ten.
• Add Shift to movement keys to select text.
• Menus and shortcut lists teach you the rest; touch typing makes it all faster.
