Touch Bar is a wonderful feature on the new MacBook Pro. Something we’d love to have on future Macs.

Here is Magic Number’s Touch Bar. (Full image here.)

It is fully customizable.
Menu ▸ View ▸ Customize Touch Bar…

Within minutes, you have a business calculator:

Or a specialized time calculator:

You get the idea.

Let’s look at the special buttons.

## Trigonometry

You may be wondering where are the inverse and hyperbolic functions.
When you tap sin for example, all is revealed:

If you don’t use hyperbolic functions, there is also a quicker way.
Check out Menu ▸ View ▸ Touch Bar Options ▸ Use Double Key

## Angle Unit

On the surface, this button switches between degrees and radians.

When you tap and hold, you get contextual options.

In radians, you can see your result in terms of pi or tau.

## Memories

Initially you have 2 memories for the Touch Bar. You can get more:

## Format

This expands into 2 parts. Part B is quite smart — it examines the context and brings you the relevant options.

## A Number formats

They are general, decimal places, scientific, and fraction.
For engineering, quantifier, and significant digits, tap

## B Contextual control

Sometimes, depending on the context of your calculation and format, you want to look at results differently. Previously you had to dig deep, now it’s one tap away.

Here are the scenarios:

## Transform

This one is good to know. It transforms a number from one form to another.

1. Sign Transform
e.g. 2 → -2
2. Inverse Transform
e.g. 2 → 2⁻¹ = ½ = 0.5
Also: cosine → secant
3. Percent Transform
e.g. 0.5 → 50%
4. Time Transform
e.g. 2.5 → 2:30

For your reference, their shortcuts are ⌘–, ⌘', ⌘%, and ⌘:

The default Touch Bar is monochrome.

If you want a colorful, vibrant Touch Bar, go to View ▸ Touch Bar Options and choose the Vibrant theme.
