Can you put the F3+ n key combination on another key in Minecraft?

I often play in creative mode and therefore often change the "game mode" with F3+ n.

Since it is very difficult to press quickly, I would like to move this function to another key. Is that possible?

Unfortunately, you can't change the key.

You have three options:

Modify the game
Download a program that makes an F3+ N macro on the desired key
If your mouse has extra keys you can do an F3+ N macro on the key in the mouse settings
