I don’t know how many Anki users are out there with Logitech G15 series gaming keyboards (mine is one of the older ones), but yes, they do work with Anki. And by that I mean that you can program the G-keys to do all the answering dirty work for you, just as you would with a controller.
Right now, I have the G1-G4 keys set up with a timed macro to hit the space bar, wait about 0.7 seconds, then hit the 1-4 keys, so it will save me an extra keystroke.
It’s one of those 微妙 kinds of things to try to make reviewing go just a tiny bit faster… or at least to make the physical aspect of reviewing juuust a bit easier. I don’t think it does a whole heck of a lot, but it makes me think it does, and that’s all that really matters. In other words, don’t go running out to buy a keyboard just to do this… but if you already have a programmable keyboard, it might be worth the effort to do it.
Then again, it might not.
Of all of the interfaces I’ve messed with for Anki, I still think the wireless gamepad controller is the best/most efficient. The tablets are nice, too, but for the absolute least amount of work, it’s hard to beat the gamepad.
