Bigram Types

SF (Same Finger)
SFs are patterns that involve using the same finger twice to hit both letters. These sequences are generally very slow and should be minimized as much as possible.

• On QWERTY, ed is a very common SFB.

LS (Lateral Stretch)
Lateral stretches are patterns that involve reaches into the outer index column with the index followed or preceded by middle finger use.

• On QWERTY, et, ct, and 'eg` are all examples of LSBs.

HS (Half-Scissor)
A half-scissor is a pattern where one finger needs to stretch or contract to press a key on the top or bottom row and another finger on the same hand stays on the homerow - but the finger that is on the lower of the two rows is either middle or ring.

• ok, sc, and rd are common examples of half-scissors on QWERTY.

FS (Full-Scissor)
A full-scissor is a pattern where one finger needs to reach to the top row and another finger on the same hand needs to contract to hit the bottom row - but the finger that is on the lower of two rows is either middle or ring.

• cr, ex, xt are all FSBs on QWERTY.

Trigram Types

ALT (Alternation)
An alternation sequence is when hand use alternates over three consecutive keypresses - either Left-Right-Left or Right-Left-Right.

ROL (Roll)

ONE (Onehand)
A onehand is when all three keypresses are pressed on the same hand, and in an order from left to right or right to left.

• asd, sdf, and fds are all onehands on QWERTY.

RED (Redirect)
A redirect is when all three keypresses are pressed on the same hand but don't occur in a smooth order.
