Can you do a zoom on a layer? & can you change state of a group?

Hi

Apologies if these are obvious or already covered. I may just be having a dim day, but....

Can you do a zoom action on a layer?

Also can you change the state of a group of items without doing lots of triggers? I have a map and I would like to show (and un-show) a set of lines when a button is pressed. All the lines start of as hidden and change in the same way. 

Thanks in advance

Hi Phil

Thanks for that. Yeah, I'd jumped in and set up layers before I got to this. But yes, that'll work.

I've just worked out I can use a layer which doesn't hide the base layer for my lines to show. Guess there's different ways of doing things and it'll take me a while to get my head around what is best for different tasks.

thanks again
