The Jump to Definition command jumps to the declaration of the symbol under the cursor. See also “Jump To Definition”. Type Alt+equal or Ctrl+double-click with the left mouse button to invoke the command. You can also right-click on the symbol and use the shortcut menu to run this command.
After locating the symbol, the symbol’s file is opened, displayed in a window, and the symbol name is selected. If you have more than one symbol with the same name in your project, Source Insight will ask you to select the one you want.
