I know I can interrupt autocomplete while working on a page but I would like to know how to completely enable or disable this feature.
You can do that for two of the autocomplete features. Autocomplete for the open square bracket and the exclamation point can be turned on or off. Autocomplete is enabled by default.
Click on your profile photo in the menu and select “Settings”. Then select “Editor” from the sidebar on the left.
Click “Edit” and then the “Disable Autocomplete” checkbox to disable it. Click “Submit”.
To enable autocomplete again, click Edit and click the check mark to remove it. Click “Submit” and autocomplete will be re-enabled.
