Hey August,
The below is what Todd Korpiva suggested on the same issue.
Suggest doing a quick search in our cow forums and chances are its already been answered 😉 Hope it helps!
The “period” key on the numeric keypad is a different key than the “period” key on the main keyboard. In fact, the one on the numeric keypad is more properly called the “decimal point” key. If you look at a laptop keyboard that still has the numeric keypad overlaid onto the main keyboard, you’ll see that both symbols (which are visually identical) are represented, side by side.
The MacBook Pro has no numeric keypad. None. Which means that you don’t have the decimal key.
I’d also consider remapping a different key to this command using KeyEd Up.
Cheers
