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".
I'm pretty certain Excel supports scroll lock. It lets you scroll the sheet with the arrow keys instead of moving from cell to cell (also last time I tried you could go to the ribbon menu with the slash key, like in the good ol' Lotus 123 days). Wouldn't be surprised if it also works in other spreadsheet programs.
