Help with scroll code in imacros

Hi guys I'm having a problem, the scroll code I have works fine but doesn't work when the browser is minimized. Can anyone help me fix this? the code is:
EVENTS TYPE=KEYPRESS XPATH="/html/body/div[2]/div/div[2]/div/div[2]/ul/li[50]/div/div[2]/span/button" KEYS="[34]"
I would really appreciate it!

You could use this to scroll down:
It should work without focus.
