This command opens the standard dialog box with the cross references to the current item. The user may select a cross reference and jump to it. If the cross-reference address belongs to a function, it will be decompiled. Otherwise, IDA will switch to the disassembly view.
For local variables, the following cross reference types are defined:
r Read w Write rw Read/Write o Reference
It is also possible to jump to structure fields. All local references to a field of a structure type will be displayed.
If the item under the cursor is a label, a list of all references to the label will be displayed.
Finally, xrefs to statment types are possible too. For example, a list of all return statements of the current function can be obtained by pressing X on a return statment. All statements with keywords are supported.
