Simpler in what way? Which of the 3 steps I outlined don't you know how to do? Hopefully, step 2 was straightforward enough. I gave you a direct example.

screen = get(handles.text1, 'String');
screen(end)='';
set( handles.text1, 'String', screen)

Care for the empty input also:
screen = get(handles.text1, 'String');
if ~isempty(screen)
screen(end)='';
set(handles.text1, 'String', screen);
end

In the callback for the delete button you would
(1) Read the string from the text box.
(2) Truncate the string like in the example below
(3) Write the truncated string back into the text box
>> str='myString'
str =
myString
>> str(end)='' %truncate
str =
myStrin
