(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}
