Preferences - Hint

The hint mode displays up to the first 40 characters of the replacement text before the space bar or enter key is pressed to activate the shortkey. Once the shortkey is initiated the hint box closes and the replacement text is inserted.

üNote: The hints are only available if the Suffix option is selected.

Show Hints when using Suffix Keys
When typing a shortkey, the hint mode displays the shortkey and up to the first 40 characters of the replacement text similar to the image below.
 

 
The hint signals that a shortkey will play back if the suffix key is pressed next. It also helps to distinguish between similarly named shortkeys such as "ap", "app", "appr", etc, so that the substitution may be seen before it occurs.
