Is it possible to reinterpret multiple keystrokes as a character?


Hello,

Is it possible to convert multiple characters into a single character? If on this particular device, I have access to only the arrow keys, could I remap and access the entire keyboard from them?

For example:
UpDownUpDownRight = A
UpDownUpUpRight = B
UpDownDownUpRight = C
etc.

Thanks.

You don't say which distro or which Dekstop Environment or Window Manager, but you might be able to do something by enabling or configuring the Compose Key. However, all examples I've seen of compose key combinations are just two keys, which in your case would give you only 16 characters. That's enough for Younger Futhark but not ASCII. How are your coding skills? You might write something to do the key translation.

I have PS/2 connected to Teensy++, connected to Kindle 3 via a 20-pin ribbon cable. I have Debian running on it, no X. Unfortunately, I can only get the arrow keys to work at the moment, and was wondering how feasible it would be to get the whole keyboard working. I have some other ideas, but I wanted to investigate this possibility since the arrow keys do work.

I'm fairly comfortable on Linux, bash and occasional kernel compilation, but mostly my skills are in web-related applications.

Thanks.

I don't see any way to use just the arrow keys to do much.

Alt or ctrl and numbers would be something.

I don't think this is going to work. Even if you use Compose, that means that one of the cursor keys would have to be used for that, so you'd be down to three. You can use more than two keystrokes with Compose, like (12), but think how long the sequences would have to be with just three keys! You can't use a keyboard driver, as that system only allows single character keys combined with a modifier, so using one arrow as a shift the other three would give just 6 letters.
