How do I make a local script activate a server script with a key down function? I know it has something to do with remote events/functions but I don't know how to use them. Please don't link to a wiki page, wiki links are blocked for me.

Remote events/function question?

Objective: Activate a server script with a local script (.KeyDown() event).
Solution: Remote Event or Function
Remote functions are recommended if you want to return a value back to the client. Otherwise, remote events are recommended.
#TO ACCESS THE SERVER
REMOTE EVENT
:FireServer().OnServerEvent:connect(func)
-- LOCAL SCRIPT EXAMPLE
Mouse = game.Players.LocalPlayer:GetMouse()
RemoteEvent = game.ReplicatedStorage:WaitForChild("RemoteEvent")
Mouse.KeyDown:connect(function (key)
key = key:lower()
if key == "f" then
RemoteEvent:FireServer()
end
end
-- SERVER SCRIPT EXAMPLE
RemoteEvent = Instance.new("RemoteEvent", game.ReplicatedStorage)
function CallThisFunction()
print("server called!")
end
RemoteEvent.OnServerEvent:connect(CallThisFunction)
-- Literally almost like any other event
#TO ACCESS THE SERVER AND RETURN A VALUE BACK TO THE CLIENT
REMOTE FUNCTION
:InvokeServer()function --[[RemoteFunction]].OnServerInvoke()
-- LOCAL SCRIPT EXAMPLE
Mouse = game.Players.LocalPlayer:GetMouse()
RemoteFunction = game.ReplicatedStorage:WaitForChild("RemoteFunction")
Mouse.KeyDown:connect(function (key)
key = key:lower()
if key == "f" then
print(RemoteFunction:InvokeServer())
end
end
-- SERVER SCRIPT EXAMPLE
RemoteFunction = Instance.new("RemoteFunction", game.ReplicatedStorage)
function RemoteFunction.OnServerInvoke()
return "server called!"
end
-- Literally almost like any other function
NOTE: Client to server communication means that an additional "player" argument will be included (first argument).
-- LOCAL
RemoteEvent = game.ReplicatedStorage:WaitForChild("RemoteEvent")
RemoteEvent:FireServer()
-- SERVER
RemoteEvent = Instance.new("RemoteEvent", game.ReplicatedStorage)
RemoteEvent.OnServerEvent:connect(function (player)
print(player)
end)
-- OUTPUT: Player instance

Unfortunately, this will be difficult to explain without using the wiki so here it goes:
Remote functions can be used to communicate between scripts, they're normally used with filteringenabled on. If you're not planning to use filtering enabled they can be sent via bind able events. However for arguments sake I will use remote functions.
You can send messages like this:
game.Workspace.RemoteFunction:InvokeServer(parameters)
And you can receive messages like this:
function game.Workspace.RemoteFunction.OnServerInvoke(ply,parameters)
--code
end
With Remote Functions the ply value is added automatically. If you wanted to send information back to a user you would have to use InvokeClient(ply,parameters) and receive messages via OnClientInvoke(parameters)
Any further questions? I'd be happy to answer them!

Bindable functions/events do not allow server-client nor client-server communication. Only "like" scripts are allowed (I'm not sure about communication between local scripts, but I've tested communication between server scripts and it worked).
Sorry but this wasn't very clear. Redbull's answer was more specific/detailed.
