What additional keyboard with programmable keys would you recommend?

Question

Keyboard

Greetings
Sometimes you often have to repeatedly press keyboard shortcuts ... I'm tired of arranging karate with my fingers. I thought about purchasing an additional mini-keyboard with programmable keys, but I can not find it. Perhaps I don’t know how to call it correctly and where to find it.
It is desirable that the keyboard works under various operating systems: macOS, Linux, Windows (mac is a priority).
Something similar to this, but universal:
What do you recommend?

Answer 1

It's called a keypad. This word googles much better. In your case "programmable keypad". There are even typesetting with interchangeable inserts on the keys. And even with small screens (Optimus Aux). A question of price.
I once bought a Razer Nostromo for similar purposes (now out of production, replaced by Orbweaver). I bought it because I really needed a CAD keypad, and this one was the cheapest. The Razer chip at that time was that it did not need firewood for the keys to work (it was needed only for recording) - they were written into the device by simulating pressing and simply reproduced everywhere. It saved me if I carried it with me and it was stupid to roll firewood for the sake of a day of digging in a computer. I don’t know how this will behave on different OS families, but I don’t think that there are too different protocols on the topic of keyboard signals. What can not be said about firewood for macros from the OS itself.
Now I have moved to 3D Connexion products in the form of SpacePilot Pro + CadMouse + a regular laptop-type keyboard. As a result, half fit on the mouse inside their software. A handy tool that even keeps track of the active window and automatically clicks profiles and macro sets + the whole SDK to make the software friendly with the controller at a lower level. However, they require software to be installed for personal settings to work anyway. And, of course, they are designed for 3D CAD / CAM systems and graphic editors in the first place, and then everything else.
Another of the solutions passed is simpler: immediately a keyboard with programmable multimedia keys. This is my home version - SS Apex. There, too, there is an interesting point: the keyboard has "layers" that can be switched along the way. Those. there are 136 keys that can be configured as you like at all, and by pressing one of them or a combination, switch to another, also a customized layout, getting another 135 functions .. and then another. I didn’t look for the limit - I stopped at two layers, although more often the second row above F1-F12 and the block on the left are enough. Without software, it also does not plow, really.

I can recommend a mouse designed for MMO games, something like this: https://market.yandex.ru/product/13972992?show-uid...

Answer 3

Any gaming keyboard / mouse from Logitech can program extra. buttons. even for specific programs.
choose by form factor / price, though you will have to invent stickers yourself
