I agree Devin

The script editor doesn’t do macro completion on return of `if` because we have so many possible variations of that it is near impossible to work out what the user wants however I know I always want `return & indent & cursor selection & return & end if` when I hit return and the last non comment word of the line is then. 

I will occasionally use the single line for things like exit repeat if I’m feeling lazy but it’s likely I only do this because there’s no macro completion here so…

Anyway, as with the macro completion of `case` -> `break` adding `if` macro completion only if the last token is `then` would require some special casing in the current code which only looks at the first token of the statement and only does completion with end <first token>.

Cheers

Monte
