You can do it by copying the edit program into your program

Print only draws text to the screen. Making it editable is not a trivial task. I recommend you take a look at edit. What do you need this for?

I am also interested in this, for like a config file, so you don't have to go into the config file to change options.

This isn't all the code, and its really basic, but here is the start of what you need to do
local function editableInput( initial, mask )
local sx, sy = term.getCursorPos()
while true do
local event, param = os.pullEvent()
if event == 'key' then
if param == key.backspace then
initial = initial:sub( 1, #initial - 1 )
end
elseif event == 'char' then
initial = initial..param
end
end
term.setCursorPos(sx,sy)
if mask then
write( string.rep( mask, #initial )..' ' )
else
write( initial..' ' )
end
end

@TOB What exactly is the mask? Like I see where is it used, but don't fully understand what it is.

Its like when you do read( '*' ) for password input. it "masks" the input.@TOB What exactly is the mask? Like I see where is it used, but don't fully understand what it is.

if all you want is a single line of editable input, basically read() that can be pre-loaded with a value, you can simply queue an up arrow key event before calling read, and pass the initial value in a table as the 2nd argument to read, as so:
os.queueEvent("key",keys.up)
read(nil, { "initial value" })
