That's clunkier though, and there are a number of laptops that don't have scroll lock at all.
Some don't have it written, but they have a padlock icon on one of the function keys (on some dells it's fn+f5 for example, on Toshiba satellite it seems to be fn+f10) so you don't necessarily know you have it.
You can remap it so it's not scroll lock as well. Is it because some of them have "keyboards" that it's needed for some games and not others?
