Unable to ignoe block of text

Hi

Cattools 3.10.0

I'm comparing Fortigate config on daily basis.

i have managed to ignore a single line, but i can't ignore a block of text (containing the ssl encrypted keys).

I have tried [start]-[stop] or {start}-{stop} with or without regex, no go.

I Need your wisdom on this.

what have i missed?

Thanks

Eran
