​​After selecting text, you can start typing immediately to replace the text – you don’t have to press Delete first.

Editing
You can really speed up text-editing by using the Ctrl keyboard shortcuts to copy and paste text.

Ctrl+C, Ctrl+Insert – Copy selected text.

Ctrl+X, Shift+Delete – Cut selected text.

Ctrl+V, Shift+Insert – Paste text at cursor.

Ctrl+Z – Undo.

Ctrl+Y – Redo.

​​Formatting
Formatting shortcuts only work if the application or website you’re using supports text formatting. If you have text selected, the shortcut will apply the formatting to your selected text. If you don’t have text selected, the shortcut will toggle the associated formatting option.

Ctrl+B – Bold.

Ctrl+I – Italic.

Ctrl+U – Underline.

Functions
These function keys are common to most text-editing applications. If you use them in your web browser, you’ll open your browser’s associated dialogs.

Ctrl+F – Find. This opens the find dialog in most applications to search for text — I’ve even seen it work in some applications that didn’t have a Find option in their menus.

F3 – Find next.

Shift+F3 – Find previous.

Ctrl+O – Open.

Ctrl+S – Save.

Ctrl+N – New document.

Ctrl+P – Print.

These keys work in most applications, but are particularly useful in text editors:

Alt – Activate application’s menu bar. You can use the arrow keys to select a menu option and the Enter key to activate it.

Alt+F – Open File menu.

Alt+E – Open Edit menu.

Alt+V – Open View menu.
