Bind extra keys on gaming keyboard

Just got a Thermaltake gaming keyboard and I'm curious if there is a way to make use of a few extra keys to record macros. I'm on 18.04, btw.

Can anyone point me in the right direction?

P.S. No, I'm not going to use it for gaming but create shortcuts to some commands for doing work. Like just pressing one of the extra buttons to cut instead of pressing both Ctrl+X.

EDIT:

I intend to use a few of these keys for my own macros:

Pardon the dust. It's second- hand.

I tried Autokey but it does not detect any of the T1 to T5 keys.
