You could print out a list of items

Spoiler

-> Choice A <-
Choice B
Choice C

and then read out the key wich was pressed by the user. Then you change the variable saving wich Item is selected and reprint the list

pressing DOWN

Spoiler

Choice A
-> Choice B <-
Choice C

if the user preses Enter or so yould just read out what was currently selected.

Hope that's what you've been looking for

print("Choose a safe:")
while true do
term.setCursorPos(1,2)
term.clearLine()
local safe = read()
if safe == "1" then
print("Opening safe 1...")
--Open safe 1 here
break
elseif safe == "2" then
print("Opening safe 2...")
--Open safe 2 here
break
elseif safe == "3" then
print("Opening safe 3...")
--Open safe 3 here
break
else
print("Enter a number.")
sleep(2)
term.clearLine()
end
end

local s = 1
while true do
term.setCursorPos(1,1)
for i=1, 3 do
if i == s then
print("[Safe "..i.."]")
else
print(" Safe "..i.." ")
end
end
local event, p1 = os.pullEvent("key")
if p1 == 200 and s > 1 then
s = s - 1
elseif p1 == 208 and s < 3 then
s = s + 1
elseif p1 == 28 then
print("Opening safe "..s.."...")
if s == 1 then
--Open safe 1
elseif s == 2 then
--safe 2...
elseif s == 3 then
--safe 3...
end
end
