I have been practising typing the standard row of numbers with these ruby scripts. My rationale here is that the simplest drills offer the greatest concentration.
Call a script from the command line, to get ten tests, with ten randomised numbers. Each test scores a point out of ten, and there is a timing in seconds at the end.
Recommended order to practice the number combinations: typing56.rb – extended positions for both index fingers, typing67.rb – right index finger home and extended, typing45.rb – left index finger home and extended, typing7890.rb – right hand home position, typing1234.rb – left hand home position, typing4567.rb – left and right index fingers, home and extended, typing67890.rb – right hand home position and extended index finger, typing12345.rb – left hand home position and extended index finger, typing#.rb – single digit numbers for all ten keys, typing##.rb – double digit numbers for all ten keys, typing###.rb – triple digit numbers for all ten keys.
