## Description

**Spell Checker** helps you correct spelling mistakes without leaving the keyboard. Press **Ctrl+Space** at the end of a misspelled word to open suggestions, navigate with **J** and **K**, and apply a correction with **Enter**, **Tab**, or **Space**. It works in standard inputs, text areas, and rich text editors, including contenteditable fields.

Spell checking runs entirely offline using a bundled Hunspell dictionary, so nothing you type is sent to a server. With no accounts or ads, this open-source Firefox add-on provides private, keyboard-first spelling assistance wherever you write.
