My one-hand keyboard software. Based on muscle memory, learn in ~5 min.
It's based on two-hand touch typing muscle memory, which means if you're already a touch typist you'll be able to type -- fast -- with one hand in minutes. http://www.staylimber.com 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…
My one-hand keyboard software. Based on muscle memory, learn in ~5 min. launched on March 30, 2011 with 16 votes, #57 of 272 launches that month and more than 75% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
My one-hand keyboard software lets people type with a single hand by remapping characters to mirror the two-hand touch typing motions they already know. When typing a right-hand character with only the left hand available, users type the left-hand equivalent instead, which uses identical finger movements. The software is designed for anyone who can touch type and needs to type with one hand due to injury or limitation, enabling fast typing within minutes of learning the system.

I type really fast, 185+ wpm, but I never learned to optimize for typing properly. I use 3 fingers on my right hand and all 5 on my left, and now I can't unlearn it. This quick test shows if your right or left hand types faster, and compares it to everyone else's results! Fun little bit of information.

My buddy paulsingh and I have been working on this for a few weeks, got something up and running and wanted to show you. The problem we're solving: When you need customer service (your flight got canceled, strange fees on your bill, etc) you just want to talk to a real person. Waiting on hold wastes your time AND your concentration; you can't be coding in the zone when part of your brain is waiting for an operator. Our solution: We wanted to make it "one click" to reach a real person. How it works: You click on who you want to talk to (even a specific department, like the billing dept at…

I recently decided to try out Google Tasks as my only task management system, and while I find some things about the interface great, it really isn't suited for someone like me who has multiple lists with lots of elements on each. So, I whipped this together real fast and I can't imagine using Google Tasks without it anymore. I realized you might want it too, so I put it on the web. Enjoy :)
