In applescript how do i get two different things to repeat at the same time I am trying to get two different actions to repeat at different intervals but right now only the first action will repeat. 

repeat
        keystroke "i"
        delay 44
    end repeat
    repeat
        keystroke "o"
        delay 5.5
    end repeat


thank you!
You could take advantage of the fact that 44 is evenly divisible by 5.5 and use an inner and outer loop:

repeat
    keystroke "i"
    repeat 8 times
        keystroke "o"
        delay 5.5
    end repeat
end repeat


Note that for the keystroke command to work, you need to be in a tell block for the System Events application.
