Las palabras y los botones cambian el tamaño de fuente de acuerdo con estas reglas:A^▲ᴀ^▼

1. El tamaño de fuente inicial es 11.
2. Si se presiona cuando el tamaño de fuente es 1, el tamaño permanece 1.ᴀ^▼
3. El tamaño de la fuente cambia con 1 punto en el rango de 1 a 12.
4. El tamaño de fuente cambia con 2 puntos en el rango de 12 a 28.
5. Las opciones son 28, 36, 48, 72 y 80 en el rango de 28 a 80.
6. El tamaño de la fuente cambia con 10 puntos en el rango de 80 a 1630.
7. El tamaño de fuente cambia con 8 puntos en el rango de 1630 a 1638.
8. Si se presiona cuando el tamaño de fuente es 1638, el tamaño permanece 1638.A^▲

Explanation

11:         % Push [1 2 ... 11]
9:          % Push [1 2 ... 9]
E10+        % Times 2, plus 10: gives [12 14 ... 28]
'$*H'       % Push this string
o           % Convert to double: gives ASCII codes, that is, [36 48 72]
8:163       % Push [8 9 ... 163]
10*         % Times 10: gives [80 90 ... 1630]
1638        % Push 1638
v           % Concatenate everything into a column vector
11          % Push 11
ih          % Input array and concatenate with 11
l180h       % Push [1 180]
&Ys         % Cumulative sum with limits 1 and 180
0)          % Get last value
)           % Index into column vector of font sizes. Implicitly display

Why emulate when you can do?!

Declared function in the ThisDocument module that takes input n in the form of Array(true,true,false,true) and outputs to the Word font size selector :P

Golfed:

Sub a(n):Set f=Content.Font:For Each i In n
If i Then f.Grow Else f.Shrink
Next:End Sub

Ungolfed:

Sub a(n)
    Set f=ThisDocument.Content.Font
    For Each i In n
        If i Then 
            f.Grow 
        Else 
            f.Shrink
    Next
    ''  Implicitly output font size to MS Word Font Size Selector 
End Sub

Thanks

-21 thanks to @Adám (removed Selection.WholeStory: call)

-10 thanks to @Adám (assume clean environment; remove f.size=11: call)

-14 thanks to @Adám (cheeky output word font size selector)

-2 thanks to @Adám (bool ParamArray)

-13 for changing ParamArray n() to n and expecting input as Boolean Array

-2 for moving from a code module to the ThisDocument module

Takes input n as a ParamArray, in the form of true,true,false,true and outputs word vbe immediates window

Sub a(ParamArray n()):Set f=Selection.Font:For Each i In n

Older version, 199 Bytes

Takes input in the form of 170,-4,6,-1 (accepts numbers larger than 1 in magnitude)

Sub a(ParamArray n()):Selection.WholeStory:Set f=Selection.Font:f.Size=12:For Each i In n
If i>1 Then
For j=i To 0 Step -1:f.Grow:Next

JavaScript (ES6), 103 101 bytes

Takes input as an array of -1 / 1.

a=>a.map(k=>[1,12,28,36,48,72,80,1630,1638].map((v,i)=>n+=n>v&&k*[1,1,6,4,12,-16,2,-2,-8][i]),n=11)|n

Test

let f =

a=>a.map(k=>[1,12,28,36,48,72,80,1630,1638].map((v,i)=>n+=n>v&&k*[1,1,6,4,12,-16,2,-2,-8][i]),n=11)|n

console.log(f([]));
console.log(f([1]));
console.log(f([-1]));
console.log(f([1,1,1,-1,1,1,1,1,1,1,1,1]));
console.log(f(Array(2000).fill(1)));

Python 2, 111 107 bytes

i=10;r=range
for d in input():i+=d*(0<i+d<179)
print(r(1,12)+r(12,29,2)+[36,48,72]+r(80,1631,10)+[1638])[i]

Requires input to be in the [-1, 1, 1, -1, ...] format. It works with the examples for some bytes extra:

for d in input():i=min(max(0,i+d),179)

Octave, 93 89 87 bytes

The input array can have integers larger than 1 or smaller than -1 to represent multiplicity of action

L=11;for k=input(''),L=min(max(L+k,1),180);end;[1:11 [6:14 18 24 36 40:5:815 819]*2](L)

Thanks to Adám, Changed language to Octave only to be able to use direct indexing into an array.

Ruby, 106 bytes

I managed to shave a couple of bytes off the python solution (and it took a while of shaving).

->n{[*1..12,*(14..28).step(2),36,48,72,*(80..1630).step(10),1638][n.inject(11){|a,b|[0,179,a+b].sort[1]}]}

It's an anonymous function that takes the input in the form of [1, -1, 1, 1, ...]. It seems to deal quite well with input in the form [170,-12] as well, but I can't guarantee it will work 100% of the time, so I'll play it safe and say it works with [1, -1, 1, 1, ...].

Tricks I used:

• [0,179,a+b].sort[1]: This clamps a+b to be between 0 and 179, which are the valid indexes of the font-size array.

• Using the splat operator on ranges converts them into arrays, so the available font sizes is generated from [*1..12,*(14..28).step(2),36,48,72,*(80..1630).step(10),1638]. Which is a flat array containing the values from each of the flattened elements:

  • 1..12 is a range from 1 to 12 (inclusive). The splat operator turns it into the values 1, 2, 3, ..., 11, 12.
  • (14..28).step(2) is an enumerator for the given range, where each step goes up by 2. The splat operator turns it into the values 14, 16, 18, ..., 26, 28.
  • The individual values (36, 48, 72, 1638) are all concatenated in their position into the great font-size array.

• I used the inject(/reduce) method, which uses each element of the input array, while reducing them down into a 'memo' variable (as ruby puts it). I initialise this to 11, and the body of each inject iteration is to set this memo variable to the result of adding the current element of the input to the current memo value, and then clamping it between 0 and 180.

All hail the splat operator!

PHP, 116 bytes

first generates the size index (from 1 to 180 inclusive),
then maps that to the point size and prints the result.

for($s=11;$d=$argv[++$i];$s=min($s+$d,180)?:1);echo$s>12?$s>20?$s>23?$s*10-160-2*($s>179):24+(12<<$s-21):$s*2-12:$s;

takes +N and -1 from command line arguments.
(-N is also accepted; just take care that the size does not hop below zero!)

Run with -nr.
