A text editor is a program for typing, editing and saving text (for example, Word or LibreOffice Writer). When typing, you use the cursor, a blinking line that shows where the next character will appear. Press Enter to start a new line, and Backspace or Delete to erase a character.

To do something with part of the text, you first have to select it: drag the mouse over the text while holding the button. A selected piece can be copied (Ctrl+C), cut (Ctrl+X) and pasted somewhere else (Ctrl+V). If you make a mistake, Ctrl+Z undoes the last action.

Formatting means changing how the text looks. You can choose the font, size and colour, and make text bold (Ctrl+B), italic (Ctrl+I) or underlined (Ctrl+U). The alignment of a paragraph can be changed too: left, right, centred or justified.

To make a neat document, follow a few simple rules: make the heading larger and bold, choose one easy-to-read font for the main text, and do not use too many colours. When the document is ready, save it with a clear name.

Key takeaways

  • A text editor is used to type, edit and save text.
  • Text must be selected before you can act on it.
  • Ctrl+C, Ctrl+X, Ctrl+V and Ctrl+Z are the most useful shortcuts.
  • Formatting changes the font, size, colour and alignment.
  • A finished document should be saved with a clear name.

Practice tasks

  1. Write a short text about yourself, 4–5 sentences long, in a text editor.
  2. Format the heading as 16 pt, bold and centred, and the main text as 12 pt, left-aligned.
  3. Copy one sentence and paste it three times, then undo the last paste with Ctrl+Z. Explain the result.
