...what is it?
• Something you did today
• You’ve been paid to do it
• You’ve probably never really practiced it in your life...

Motivation
• I’m a programmer - I have a lot of typing to do!
• Fear of RSI - colleagues have been crippled by it
• Statistic: “In the USA, carpal tunnel syndrome results in anaverage of $30,000 in lifetime costs” (Wikipedia)

To business!
• Just need to grab some typing programs
• Get down to learning QWERTY the right way!!

Undefined
• Didn’t know how long it would take
• Is this really the best idea?
• Hard practicing QWERTY the right way at night, then going
back to old habits during the day

The First 20 Hours : Rapid Summary
• Nearly any skill can be learnt (to a useful degree) in 20 hours
• A couple chapters of general how-to, then one chapter on each
of six skills he learnt with his method
• One of these was on touchtyping... in ‘Colemak’

QWERTY
• “Slowly took over the world”, since 1872. Main design con-
straint: to stop typewriter key bars jamming.

DVORAK
• 1932 design for an optimal layout.
• Relatively hard to learn.

Colemak
• Designed by a programmer with a mathematical model and lots
of spare time.
• Trade-off between ease of transition (Q,W,Z,X,C,V stay the
same) and optimization.

Method
• Swap keys on OS and keyboard
• Get some training programs
• Don’t give up before the 20 hour mark

Programs
• A variety is useful
• Practice different subskills - hardest keys, whole prose, etc.
• Data export is not much of a feature. Many record your WPM
+ accuracy, but often only for own graph feature.
