    * *Lua* — bytecodes are hidden, revealed on click on a source line

    * *Bytecode* — only bytecode is displayed

    * *Mixed* — bytecodes interleaved with Lua source code

 1. browse generated JIT-compiled traces

    * visually examine trace graph

    * highligh source code lines and/or bytecodes participating in a trace

 1. examine trace properties, including general info, IR and the assembly
