Your interpretation of "entry differences" is that the same key presses are displayed different but should yield the same result. That is not (and should not be) correct. The correct interpretation is that they are different entry modes so that you would have to enter your input differently in order to get the same results using a different entry mode. For example, in RPN mode I cannot press the keys [2] [+] [3] in that order and have it yield the same result as in algebraic mode (the former leads to an error and the latter correctly yields 5). In textbook mode, an integral (using the template) is entered very differently from algebraic mode, so trying the same sequence of keys would assuredly not give the same results (in textbook mode, if you use the template, you actually have to navigate with the arrow keys).
