No questions for now
Oh and please answer questions in this format:

Spoiler

#1: bla bla bla

#1: RichardG had the turtle make the computer a peripheral (peripheral.wrap("front")) and then have it reset, which I think is something like per.shutdown(), per.start(), where per is the variable for the wrapped computer.

#2: That depends on what you are doing, but most times, you are going to be using os.pullEvent("key"), which will wait for a key to be pressed. Then, just have an if statement looking for those specific keys, and have them do what you want.

#3: You can find this in the config file. For most programs, though, you will want to check it, by using x, y = term.getSize(). The x variable will be the number you are looking for.

1. You can use the Peripheral API, since computers and turtles are treated as peripherals.
2. You would want the os.pullEvent() function.
1. Like this:

   
   				local event,p1 = os.pullEvent()
   				if p1 == KEYCODE then
   				--do stuff here
   				end
   				

3. What do you mean how many columns?
