This is a brief explanation on how to learn chords. The method works for me.

The fingers are named PRMI-T-IMRP: Pinky,Ring,Middle,Index (Left) - Right Thumb - Index,Middle,Ring,Pinky (Right). Left thumb is holding Alt, Shift, Control. Right thumb is for Fun, Num, Shift.

To enter, for example, T, press _MI-_-___:

For G, press __I-_-IM__:

Z is infrequent letter, so it is assigned to P__-_-__P:

For people like me, who have trouble with pinky synchronization, two alternatives provisioned _MI-_-_R_ and _MI_-T-__P. The latter is convenient if a word starts with capital Z after a space.

The "manipulation" chords are in the separate column on the charts. The example below is for PRINT SCREEN

("from left to right and top to bottom"):

DELETE button is P__-_-__, and BACKSPACE is __-_-__P.

There are dedicated chords for COPY (Control-C) and PASTE (Control-V):

PRM_-_-__ - grab selection with left hand (COPY)

___-_-_MRP - release with right hand (PASTE)

The double quote: "" is __MI-_-IM__. Just remember this nice fellow:


1. I started by learning the primary chords and punctuation for 40 minutes:

Real oiler lair,
Oil or ore are a lie.
Oral lier -- lira ear?
Ale or roe are a lire!
Earl or liar are a role;
Air rail oiler:

2. On the same day, added two-finger chords (1 hour):

horse tail
loan shift
herbalist inflators
tensorial baritones
life boats hail stone
tail bones orientals
forestial inflaters
botaniser labor
fire boats
halftone abolisher
frost line relations
biathlon loafer
obtainers refashion horntails
shift table sabotier
inflater laborite
alerions inflate
boar or fish
flariest searobin
seafront notaries
baronets foresail tables
insolate rats in holes
banisher liberates laborists
hotlines on the inflation
oriental lots
sortable orbitals
reinstal airholes
aera borealis
relation brothels
lifeboat shoals
antihero florist

3. On the next day, added the rest of the chords, with 1-hour practice. By the day end the entry speed was at 10 WPM.

By that time, the table was not needed for the letters, although I kept it handy for characters like @#$&`\~|=^/*
