# **XrefXpert** 🛠️  
**An advanced cross-reference navigation tool for IDA Pro.**

## **Overview**  
XrefXpert is a powerful IDA Pro plugin that enhances cross-reference (xref) navigation by providing a **dockable window** displaying all references to a function. It allows quick navigation between xrefs and **auto-syncs** with the pseudocode window for efficient reverse engineering.

✅ **Instantly list cross-references (xrefs) to a function**  
✅ **Click an xref to open it in the pseudocode window**  
✅ **Use hotkeys (`Shift+X`) to jump between xrefs**  
✅ **Auto-scrolls and highlights the current xref**  
✅ **Docked to the right of the pseudocode window for quick access**

✅ **Filter on Immediate Values**  
✅ **Filter on Parameter Counts**  
✅ **Filter on Binary Signatures**
