The Identifiers panel displays all identifiers currently available:
This includes variables (including constants and custom functions), system functions, and operators. By default only non-system variables are shown, but this can be changed using the context menu:
By double-clicking a variable, its value is displayed in a console window, a diagram viewer, an image viewer, or a sound player depending on the type of the variable. A custom function is displayed as its AST.

|Ctrl+C||Copies the value to clipboard|
|Ctrl+S||Saves the value to file|
You can select any number of variables and chose to delete these. You get a confirmation dialog box before anything is actually deleted:
