Summary of My Typing/RSI Experience 1992 – 2013
i have 3 rounds of close to Repetitive Strain Injury (RSI) experience. Never had any pain, but definitely tingling.
1st time is in 2005, that's due to using laptop all the time for a year. I wrote about it here: How to Avoid the Emacs Pinky Problem
2nd time in 2010, eventually found the problem to be a bad habit of pressing the 1, 2 keys, by turning my left hand wrist sideways and using index finger to press the 1. Documented here Programer Hand Health: vi Esc Key Syndrome
3rd time in 2012. Eventually found the reason to be pressing the x key too much on a rubber dome keyboard. Documented here: The Roadmap to Completely Replace Emacs's Key System, Part 1
now, i don't have any problem. But also, i'm now using a radical ergonomic keyboard, mechanical keys, ErgoEmacs minor mode, also Dvorak layout, and there are only 5 of emacs default keys that i still use: the arrow keys and sometimes F1.
here's a summary of my typing experience.
• 1992. Started typing as a data entry clerk.
• 1994. Started using Dvorak 〔➤see Dvorak Keyboard Layout, My Experience ⌨〕.
• 1998. Started using emacs, and basically live in it by 1999. 〔➤see My Experience of Emacs vs XEmacs〕
• 1998 to 2005: Use emacs in text terminal only, all default keys. (started to use GUI emacs in 2006)
1992 to 2005. Never had any typing/RSI problem. Am using standard PC keyboard. Most of these years using whatever the keyboard that comes with Mac.
• 2005. 1st brush of RSI. Caused by always using a laptop (Mac iBook) since 2004. Solution: bought the Microsoft Natural ergonomic keyboard. First time using a “split” keyboard. Never liked ergonomic keyboard before, but now, i NEVER want to type on non-split keyboard.
• 2007. Started to devise and use ErgoEmacs mode
• 2009. Switched keyboard from MS Natural to Microsoft Natural Ergonomic Keyboard 4000.
• 2010. 2nd brush with RSI, due to bad habit of pressing the keys 1, 2 keys, induced by the Microsoft 4000 keyboard. Documented at Programer Hand Health: vi Esc Key Syndrome
• 2012. 3rd brush with RSI. Cause: pressing the x key too much on a bad rubber dome keyboard (the MS 4000). Documented here: The Roadmap to Completely Replace Emacs's Key System, Part 1
• 2013. Started to use Truly Ergonomic Keyboard. Love it.
• 2013. Started to use a emacs keybinding system that is all single key press sequence, except for about 10 commands that make sense when held down (➢ for example:
forward-word) in ErgoEmacs mode. A preliminary report at The Roadmap to Completely Replace Emacs's Key System, Part 2. Eventually i'll publish the final key system, or incorporate it as part of ErgoEmacs mode.
or, buy something from my keyboard store.
