How to use the instruction editor: 1. Load an .ELF file 2. Select an instruction from any valid memory address inside any thread. 3. Press 'E' key and have fun. :P Note1: I suggest to remove the function InterpreterDisAsmFrame::DClick and use InterpreterDisAsmFrame::InstrKey to do all debugging-related actions (Add breakpoint, Edit, Step, Run, etc.) using the same keyboard layout as debuggers like OllyDbg. Note2: The final binary is 200 KB larger due to this feature. This issue should be fixed in the future. This has probably something to do with the #include's.
