Mapping for home button

[ClaudiuIO]

Sorry if this is a silly question, but is there a way to create a mapping for home? Like by default in ChromeOS it is alt + left?
I tried to add a line to /etc/keyd/default.conf like below and then restarted keyd but nothing seems to happen:

alt + left = home

I am on Pixelbook Eve with Manjaro if that makes a difference.
Thank you in advance for pointing me in the right direction.
