Show HN: My one-hand keyboard software. Based on muscle memory, learn in ~5 min.

How it works: Examine how the keyboard is laid out. The motion you use to type "G" is the same motion you use to type "H". Index finger, home row, towards the center of the keyboard. Same with "E" and "I": middle finger, top row. It's the same motion, but with the other hand.
Let's say you broke a few fingers on your right hand. You can only use your left hand to type. Using Limber, all left-hand characters are typed normally. When you come to a right-hand character, type the left-hand equivalent instead. It's the same motion as the key you should be typing, the only difference is that you're using your good hand instead of the injured one.
Our brains are amazing. Your left hand already has the muscle memory to type right-hand characters. It's kinda like that thing where you can't draw a circle with one hand and a square with the other at the same time. The wires are crossing somewhere.
So, for example to type "this" you would hit the keys "tges". Left-hand characters are typed normally, and for right-hand characters type the left-hand equivalent instead.
So the raw key input "tges" is gibberish, made up of all left-hand keys. My software runs predictive text algorithms as the input is coming in. So it always appears as if you're typing the most likely word, "this".
Who it's for: For hackers. Stay productive and code while your finger is sprained or your arm is in a cast. Also for recent amputees and other permanent injuries. Or hold a baby in one hand, type with the other. Or mouse with one hand, type with the other. Etc.
Try it out! Free trial on the website. It's an unlimited trial, but makes you wait 60 seconds after you type too many words. Windows only for now, let me know if you want a Mac version in the comments.
I'm very excited to get this out there. Let me know what you think. Would you ever use it? Pay for it? Get your company to pay for it? I'm open to any and all criticism/suggestions/ideas, from the base concept to any typos on the website. Thanks!
