Start all Timelines within a Group

Scripting is your friend - though there is no clean way in the LUA API to see what timelines exist, so you will need to cycle through a relevant large number to find them.

Create a startup script

groupA ={} --a matrix with all group A timelines

for i = 1, 20 do --for all timelines in your project
    if get_timeline(i) then --if a timeline with that number exists
        if get_timeline(i).group == "A" then --check if it belongs to group A
            groupA[#groupA+1] = i --add it's nubmer to the table
        end
    end
end

function StartA() --declares a function
    for i = 1, #groupA do --for all numbers in the group
        get_timeline(groupA[i]):start() --start the timeline
    end
end

StartA() --runs the function StartA

Where do you find the group letters?   The Group pull down box in most Trigger sections only have colors.  Then you get into the Action section, and it pops up with Group A, B, C, ect...  How do you know what color is what group??

Timeline> Manage> Click on timeline > Groups

Timeline> Manage> Click on timeline > Groups

Trigger color groups are for organizational purposes and is separate from timeline groups. 

Thanks Stefan,  that makes a lot more sense now.  And it also make sense why my release others commands aren't doing jack....  I don't have any groups assigned!!
