# Show tooltips for simple values

To display the value of a simple variable, hover the mouse pointer over its name in the code editor.

To keep the tooltip visible, select the pin button. You can expand pinned tooltips to view their full content.

Pinned tooltips are stored in the session. To close all pinned tooltips, select Close Editor Tooltips in the context menu in the Locals or Expressions view.

To disable tooltips for performance reasons, go to Preferences > Debugger > General > Use tooltips in main editor when debugging.
