Method to see list of open charts and change the active chart

I need some script code that will allow me to see a list all the open charts (Symbol & Timeframe). And then I need a way to change which chart is active or how to see objects on the other charts if I don't need to shift the active one. Ultimately I want to access objects on various charts and save the object details into global variables so I can replicate those objects onto another chart, in affect merging objects onto a favorite chart. This would be done in two steps, one script saving approrpriate variables and another script to read those variables, creating new objects on a designated chart.

But the stumbling block is shifting focus or accessing the objects on a different chart from the one the script is tossed on. I can grab the objects from the first chart, it is the next n charts that pose the problem.
Thanks for any help given!

I use the dropdown from the Windows choice on the main menu. It only lists 9 active windows, but thats more than enough for me.

Getting a list of objects is more difficult and I don't think I understand because a trend line on one chart has no relevance to another chart. It is very specific to the chart it was drawn on. Same with Fibo lines, Fractals, MAs...

If you or someone you trade with does an extensive work up on a bunch of charts and you want to merge all of that work with some other chart that has a different work up or a bunch of indicators of any other extensive setup then it can be very useful to blend the two charts together.

And it can apply to trend lines, fibs and other objects. A trend line on one EurUsd chart can be copied accurately to another EurUsd chart and be totally relavant. If there are many objects then an automated method to copy them can save a huge effort freeing more time to do other things.
