How to get the Chr/String of a Mouse Button Ascii

[omni]

So I'm working on a project and I would like to have a way to set a button like enter or mouse left click to a variable and use that variable to check _IsPresssed. Simple, I can do that. But I want a readout showing what button you are using. I thought _hextostring would work but It gives me a weird symbol for the left click ascii and Chr(Dec($sHex)) doesn't give a result at all. What could I use to show what button you've set if all i have is a $sHex?
