A Morse code machine you can press.

Learn Morse, write messages in it, and key it anywhere on your Mac.

The Dot & Dash machine in Silver: a thin aluminium key with a knurled knob, its paper tape printing SOS in dots and dashes.

Press the key.

Hold Space or press the knob. A tap is a dit, a hold is a dah. Try SOSSOS, keyed on the machine. On a Mac, you key it yourself.SOS on the machine’s tape. In the app, you key it yourself.

Learn Morse by keying it.

Twenty short chapters take you from E and T to the whole alphabet, the figures, everyday punctuation and the common prosigns. A lesson takes two or three minutes: meet a letter by its rhythm, key it, then key real words with it. Get one right and the next comes up by itself.

A Learn lesson in chapter 5: L keyed right at 12 WPM, the next letter on its way. Behind it, Progress shows the letters known so far in blue.
Practice
A five-minute daily review brings back the characters that need it most.
Progress
A quiet map of the alphabet shows what you know, and how fast you key it.
By ear, later
Copying by ear waits in Practice as an advanced drill, for when you want it.

Write messages in Morse.

Type a message and the machine sends it: the lever moves, the tone plays and the tape prints. Or key it yourself and watch it decode as you go.

Write with MEET ME AT NINE keyed on the machine, the seven finishes under it. Behind it, the Library in Midnight holds earlier messages.
Straight key or paddles
Hold Space, or use two keys as paddles in iambic mode A or B. A USB key or keyer that types a key works too.
5 to 40 WPM
Set the speed the machine and the paddles send at, and add Farnsworth spacing while you learn.
The Library
Save what you send, replay it on the machine and share it later.

Turn Morse into text, and back.

Type or paste dots and dashes and the message appears as you go. Or write the message and get its Morse, ready to copy or to play on the machine.

Transcribe twice. Left, Morse to Text: pasted code reads CQ DE DOT AND DASH. Right, Text to Morse: Hello world #2 in dots and dashes, with a quiet note that Morse has no code for the hash sign.

Key Morse in any app.

Switch on Type Anywhere in the menu bar, hold Right Option as your key, and what you key is typed into the app in front. A small pill under the menu bar prints the tape as you go.

The top of a Mac screen. Under the notch, the Type Anywhere pill prints ON MY WA and the Y being keyed; in the notes app below, On my wa has been typed.

Share the tape.

Send a message as an image of its printed tape, as audio, or as a square or vertical video of the machine printing it.

The tape image of HELLO WORLD: the machine in Midnight with its paper curling out, the message on two strips under it.

Questions

Do I need to know any Morse to start?

No. The welcome teaches E, one dit, and T, one dah, then has you send SOS. The course takes it from there, two or three characters a chapter.

What happens after the 24 hours?

Learn, Write, Transcribe, Type Anywhere, the Library, paddles and every finish but Silver wait for a licence. The machine, the reference and sharing the tape as an image stay free, and your progress and Library are kept.

Why does Type Anywhere ask for Accessibility?

macOS asks before any app can type into other apps. Dot & Dash asks the first time you switch Type Anywhere on, never before. It listens for your Morse key, and for when you type or click yourself so it never deletes your own words. It never records what you type, and it pauses in password fields.

Can I use a real Morse key?

Yes, if it types a keyboard key, as many USB keys and keyers do. Choose that key in Settings.

Does it need the internet?

No. Dot & Dash works offline. It goes online only to check your licence and to look for updates.
