:highlight style

[TerryQuiet]

Hi, I cant figure out if its possible to change theme so :highlight fields are bold or underscored.

The :highlight command doesn't support customizing the styling. You can add a config file that tweaks the theme, here is an example that bolds the word "Entered":

{
    "$schema": "https://lnav.org/schemas/config-v1.schema.json",
    "ui": {
        "theme-defs": {
            "default": {
                "highlights": {
                    "example1":{
                        "pattern": "Entered",
                        "style": {
                            "bold": true
                        }
                    }
                }
            }
        }
    }
}

See https://docs.lnav.org/en/v0.12.2/config.html#style for the details on what options are available for the style.
