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".
They are all useful, except for maybe Pause. Ctrl+Insert and Shift+Insert ist like Ctrl-C Ctrl-V, but it works in terminals too. Home goes to the beginning of the line. Shift+Home marks the line from current position until the beginning.
