Inlay Hints. General Settings
Enable Inlay Hints
Lets you either enable or disable the entire inlay hints functionality in all languages.
You can toggle this option right from the editor with the Control+Alt+Shift+5 shortcut.
Reserve press-and-hold and double-tap of the Ctrl key for Push-To-Hint
You may need to clear this checkbox if the press-and-hold and the double-tap of the Ctrl key are already bound to some other actions in your OS or other applications.
Use the selector to choose how inlay hints in all 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.
Font size scale factor
Use this selector to change the font size of inlay hints. 1.0 means the same as the editor font.
