Inlay Hints. General Settings
On this page or JetBrains Rider options, you can configure general behavior of inlay hints that will affect hints in all .NET languages.
|Enable Inlay Hints in .NET Languages||Lets you either enable or disable the entire Inlay Hints functionality in .NET languages (C#, VB.NET, XAML).|
|Reserve press and hold of the Ctrl key for Push-To-Hint||You may need to clear this checkbox if the press-and-hold of the Ctrl key is already bound to some other actions in your OS or other applications.|
Use the selector to choose how inlay hints in .NET languages should be displayed in the editor (you can override visibility for each language on language-specific pages in this section): choose Show Always or Never Show to always show or hide hints, or choose Push-to-Hint to hide the hints by default but show them when you press and hold Ctrl.
