If you have "Help" instead of "Ins", replace it with Overgod-tier. Keep pressing it, it will come.
OC, feel free to share.
EDIT; Home is now G-od tier. I didn't know it would go to the beginning of a line, I always used macros "lol".
Pressing ScrLk twice and then the number of the port switches to this port on the KVM switch in the office. Very specific use case, but still.
Pause ... I have no idea. If I remember correctly you can, well, pause terminal output with it, but I never tried.
The rest of the keys I use regularly.
