Where to enter scripting function?

[Buster]

I am fairly new to Mp3tag which i am finding is absolutely great but there are features I am little confused.

For example: I found a script to remove the first "x" of characters, where do I enter it?
$cutleft(x,n)

This is what I want to do for title name
01 - Example of Song >>> I want to change to >>> Example of Song
I want to remove the first five characters/spaces

Thank you in advance.

Field specifies the tag field the formatting rule should be applied to. Format string must have the field placeholder for the field selected above and the string which should be appended. Example: If you want to append the string " xyz" to the current value of the comment field: Action type: Format value Field: COMMENT Format string: %com…
