Decompiler Actions

The decompiler provides three primary views: Pseudocode, Microcode, and CTree Viewer, each with its own set of actions. These actions are accessible either from the top menu bar or through context menus.

To explore which actions are available from the top menu bar for each view, refer to Menu Bar Actions.

Most actions are context-sensitive and are only available when the cursor is positioned on specific elements.

Pseudocode Actions

Below is an overview of all decompiler-related actions available in the Pseudocode Actions.
