What steno keyboard should I get?

Generally, any keyboard which is in stock!

If you need to use steno on a device that you can't install Plover on, any keyboard which takes Javelin (embedded steno) would be your best choice. Other than that, this page lists the machines known to work with Plover. The main 4 choices are:

1. Dedicated hobbyist machine
2. Stenotype machine
3. Standard computer keyboard
4. Video game controller

Commercially Available Hobbyist Machines

Machines that are or will be available for purchase. As of right now, there are no hobbyist lever machines.

Stenotype Machines

Supported protocols

Plover supports several protocols that are in use by various machines:

• Stentura serial: most machines by Stenograph and many others.
• Gemini PR serial: typically any recent machine made by the Neutrino Group, such as the Piper, Revolution, or Infinity series.
• ProCAT: protocol used by all ProCAT machines.
• TX Bolt: an older protocol supported by some machines as a primary or secondary protocol.
• Treal: used only by the Treal from Word Technologies.
• Passport: used only by the Passport Writer from Advantage Software.

This means that, in theory, many machines work with Plover.

Known supported stenotypes

The following machines have been confirmed by users to work with Plover after actually trying it:

NKRO keyboards

If you don’t have a steno machine, you can use a keyboard that supports N-Key Rollover (NKRO).

What’s NKRO?

NKRO stands for N-Key Rollover. This is a feature of some keyboards whereby you can press as many keys as you want simultaneously, and they will all register. Typical keyboards stop working correctly when you press somewhere between 4 and 7 keys at once. For more information, see the Wikipedia entry about NKRO.

How do I know if my keyboard has NKRO?

In general, most keyboards will not be NKRO. “Gaming” and mechanical keyboards are most likely to have NKRO, while budget as well as laptop keyboards are unlikely to have NKRO.

The easiest way to test for NKRO is to visit https://keyboardchecker.com/ and press several keys all at once to see if they register. If your keyboard has NKRO, you will be able to press multiple keys with your palm and they will all light up as green on the website. If your keyboard does not have NKRO, several keys will not light up on the website.

What if my keyboard is not capable of NKRO?

If you don’t have a keyboard that’s capable of NKRO, but still want to give Plover a try, you can arpeggiate/roll the keyboard chords. Have a look at the Beginner’s Guide for more information.

Video Game Controller

It is possible to use a video game controller with Plover by installing the Plover Controller plugin. Please use the built-in Plover plugins manager to install this plugin. This is one of the cheapest options to get you started! If you don't have a USB or bluetooth controller lying around, you can find a used one very cheap, and you can even buy new ones for a great price.

Note: as per the project's README, there may be issues using it with macOS.
