Spell Menu
Spell Menu is a contextual menu that contains at minimum Copy and Paste options.
Within the Spell Menu are choices for corrected spellings, along with hierarchical menu choices for Spell Settings, such as Automatic Correction, Text Substution, and so on.
TBH, these features are befuddling but it is possible to garner a setting where you type TBH and it instantly replaces this with the full phrase, To Be Honest, which is bussin.
