After downloading the piaware image i noticed my keymaps were off. Ctrl+a, ctrl+e, home and end keys all didn’t work.
I found that at the end of /home/pi/.bashrc there was a command to set the readline to Vim bindings.
If you want to use your home and end keys, here’s the “fix”:
sudo nano /home/pi/.bashrc
Remove or comment out the very last line:
set -o vi
I’m not sure why this line is here, but it’s not a standard line in Raspbian, so it’s something custom to the image (which has annoyed me since I installed it) 
Hope this helps someone else!
