Is Mouse.Keydown actually deprecated?

im making an FPS and i want to make a custom inventory system, but the wiki says "KeyDown [deprecated]", so is there any other way to use a key down event if its actually deprecated?

mse.KeyDown:connect(function(key)
	
end)

i added this but i wasnt sure if it was KeyDown so i checked the wiki and found out that it was deprecated

im wondering if its still a good option or if there's another, better way to do that

any help is appreciated
