Debug Tool Window. Variables

When a stack frame is selected in the Frames pane, the Variables pane displays all data within its scope (method parameters, local and instance variables).

In this pane, you can set labels for objects, inspect objects, evaluate expressions, add variables to watches and more.

Context menu options

Inspect N/A This command is available for fields, local variables and reference expressions, and opens a non-modal Inspection window, where you can concentrate on a particular reference. You can open as many Inspection windows as required. The view in the Inspection window is the same as in the Watches pane, but requires less screen space.
Set Value F2 Use this command to change the runtime value of a field or a variable.
Copy Value Ctrl+C Use this command to copy the value of the selected variable to the Clipboard. If multiple items are selected, not only variables' values, but also their structure is copied, so that when you copy-paste the selection to a text file, the indentation mimics the tree output of the debugger to produce an easy-to-read output.

Alternatively, hover your mouse cursor over a value and view its contents in the tooltip.

Copy JSON This menu item is available only in the JavaScript context. Choose this command to copy the selected value in the JSON format.
Compare Value with Clipboard N/A Use this command to compare the selected value with the value currently in the Clipboard.
Copy Name N/A Use this command to copy the name of the selected variable to the Clipboard.
evaluateExpressionIcon Evaluate Expression Alt+F8 Use this command to evaluate the selected variable in the dialog that opens.
watches-add Add to Watches N/A This command is available for all nodes except static ones. Use this command to create an expression that references the node and add this expression to the Watches pane.
Show Referring Objects N/A Use this command to display a list of objects referring to the currently selected variable.
Jump to Source F4 This command opens the source code of the selected variable or field in the editor and places the caret in the corresponding line.
Jump to Type Source Shift+F4 Use this command to open the source code of the selected variable or field type in the editor.
