When I open a lua script
I see the menu is gray.
Where is this controlled?

These are defined by various command.xxx.$(file.patterns.lua) properties.

I have this set in SciTEUser.properties so Run executes the current file with SciTE's Lua interpreter: I think you can use dostring $(CurrentSelection) to execute the current selection as Lua.

If you want to execute with an external Lua interpreter, set the appropriate subsystem (probably 0 or 2) and command line in the command properties.

"Debug" is controlled by the command.build. properties. You can inspect ahk.commands.properties for examples.
