Right-click within Editor Window and select Options / Auto-completion.

Auto-completion gives suggestions in a suggestion window while typing. Scrolling through the suggestions is possible with the arrow keys and accepting a suggestion with Enter key. Suggestions are shown when available and can be also manually displayed with  keyboard shortcut (by default CTRL+Space). It is enabled by default.

The Auto-completion system uses a dictionary-based engine and semantic-based engine for generating suggestions.

•Dictionary-based engine - Searches in all currently open files, suggesting similar words from those files. It is available for all types of files and it has no language awareness.

•Semantic-based engine is language-aware. It is currently only available for C, C++ and Python. By default it is used only when necessary (e.g. when suggesting class members).

Enable auto-completion - Check to enable Auto-completion.

Replace rest of word - Check to automatically replace the word.

Force semantic completion - When enabled the dictionary-based engine is disabled and only semantic completion is used.
