Password combination question

[droidman]

Hi, im trying to find this but i'm not understanding the help topics i find so im going to probably repost a question, but i really need some help with this one right now.

When using the combination attack with the hashcat gui i see 2 rule boxes, left rule and right rule.
How can i combine 2 lists and play with their upper and down casing?

like list1 word 1
password
list2 word 1
test

i wanted to use a rule that would try all possible combinations with different casing like
Passwordtest
PaSwOrDTeSt
etc
is there a rule that can do this ?

thanks in advance
