Alright,so I am having huge projects,and it seams like im spamming or somthing,but im trying not to.So,my question is how do I put a text and using the arrow keys,make these () go around it and if you click enter,it will do something.So example:

MENU:

(Start) Reboot Exit

Something like that.I do also proboly want to know how to make it when you click enter,it will do something.

Here's a nice and simple menu:

t_menuOptions = {"Start", "Reboot", "Exit"}

function menu(menuOptions)
    local selected = 1
    local offX,offY = term.getCursorPos()
    local curX,curY = term.getCursorPos()
    while true do
        if selected > #menuOptions then selected = 1 end
        if selected < 1 then selected = #menuOptions end
        for i = 1, #menuOptions do
            if selected == i then
                write("("..menuOptions[i]..")")
            else
                write(" "..menuOptions[i].." ")
            end
        end
        while true do
            local e,e1 = os.pullEvent("key")
            -- Left
            if e1 == 203 then
                selected = selected - 1
                term.setCursorPos(curX,curY)
                break
            end
            -- Right
            if e1 == 205 then
                selected = selected+1
                term.setCursorPos(curX,curY)
                break
            end
            -- Right
            if e1 == 28 then
                term.setCursorPos(curX,curY)
                return menuOptions[selected]
            end
        end
    end
end

option = menu(t_menuOptions)
if option == t_menuOptions[1] then
-- Start
elseif option == t_menuOptions[2] then
-- Reboot
os.reboot()
elseif option == t_menuOptions[3] then
-- Exit
end

Ok,so I kinda was expirimenting with this,and now when ever I press <,it will change the menu options around !

You messed with the for loop didn't you?

Well, if you need help fixing it, you should probably post the revised code.
