Ok, I'm new to using AC Tools, and I've done a lot of searching, but I can't find an answer. Is it possible to hold a key during the entire macro (in my case, 'up'). Here's a example of what I'd want to do:

keyhold {up} 20sec
keyhold {left} 500
delay 1000
keyhold {left} 600

but, I'd like everything after keyhold {up} to run while keyhold {up} is still running. Is this possible?

Otherwise, I'd like to know if it's possible to run a key combination, such as keyhold {up},{left} 500

Thanks in advance.
