To turn off automatic suggestions and completions in the MATLAB Editor, on the 'View' tab in the MATLAB toolstrip, in the 'Display' section, click the 'Automatic Completions' button off. When automatic suggestions and completions are off, you can use the 'Tab' key to manually show suggestions and completions.
You can also turn off automatic suggestions and completions through the MATLAB Preferences:
- Go to the 'Home' tab in the MATLAB toolstrip and in the 'Environment' section, click 'Preferences'.
- Select 'MATLAB > Editor/Debugger > Automatic Completions' and in the 'Suggestions and completions' section, select the 'Show on tab' option.
- Click 'Apply' and 'Ok' to save the option.
The MATLAB Editor will now show suggestions and completions when the tab key is pressed, rather than showing them automatically.
