Chording approach

In order to distinguish normal typing from a chord, chordgen defines chord, shift, and alt1 / alt2 keys that are pressed in combination with the chord to get the desired output. These keys work well on the thumbs to ensure all the combinations are possible.

Input	Output
l + chord	look<space>
l + chord + shift	Look<space>
l + chord + alt1	looked<space>
l + chord + alt2	looking<space>
l + chord + alt1 + alt2 (alt3)	looks<space>
l + chord + shift + alt1 + alt2	Looks<space>

This is how I have set up my 4-key thumb cluster from left to right:

• alt1 — normally tab on tap or my navigation/number/symbol layer on hold (hold preferred).
• alt2 — normally space on tap or my media/function layer on hold (tap preferred).
• shift — normally backspace on tap or shift on hold (hold preferred).
• chord — normally delete word; great when making mistakes while learning.
