(1) I don't know.

(2) An easy thing to do is to change the display magnification at the
bottom of the workbook window or use the menu command

 Window | Magnification


(3) Until assigned a value, what you type is a Symbol.


Head /@ {word, 2, Pi, Pi // N, 3.14, 1/4, "str"}


{Symbol, Integer, Symbol, Real, Real, Rational, String}


#[word] & /@ {Head, StringQ, NumericQ}


{Symbol, False, False}


word = 2;


#[word] & /@ {Head, StringQ, NumericQ}


{Integer, False, True}


word = "str";


#[word] & /@ {Head, StringQ, NumericQ}


{String, True, False}


word =.


#[word] & /@ {Head, StringQ, NumericQ}


{Symbol, False, False}
