Anyone tried a rotary switch as a left and right arrows?

[KTKM]

It's really annoying when coding or typing and having to go back just a few steps for a small fix, so I thought of adding a rotary switch to a small 2-3 key keyboard to work as arrows on the left side of my main keyboard.

Did anyone try that? if yes, do you find it useful?

Lastly, will it work with 2-3 keys connected using a ATTINY85 cheap controller?

Check this out bro. I haven't used it myself but it may be useful for your issue.

To do this you'll need to find a switch that effectively pushes the lever to one side or the other then returns to a central position - if you can find one of those it will work just fine, and if it has a definite click when this happens I think I'd like it.

Most rotary switches work by connecting different pins as they go round though, so the computer would see a key held down which would not be any use.  I guess the switch you're looking for would have a special name but a quick search has revealed nothing.

For 5 keys (3 standard and 2 on the rotary) you would need 5 I/O pins making a 3x2 matrix, so you could add another switch too if you wanted

That's basically what I want to make but smaller and at a much cheaper price.

There must be a way to make something like the Powermate without the many pins I see on most rotary switches.

I found something that might work, so for future reference: google: KY-040 Rotary Encoder
