Description

chordal hold as-is

Chordal hold https://docs.qmk.fm/tap_hold#chordal-hold-handedness

Chordal hold configuration allows for keys to be assigned as L, R or *. Where * configures a key as exempt from the opposite hands rule.

requested change

With this feature request i ask for one additional value to be added, for the inverse of *: to configure a key as always affected by the opposite hands rule.

I'm not picky about the value, but since I'm opening the request: how about ! for the added value?

My particular Usecase:

After spending some time on home row mod configuration, i noticed the responsiveness of my repeat key was better with one half of the keyboard than the other. A bit of deduction brought me to the Chordal Hold configuration where i found things as described. I would like my repeat key to settle mod-tap keys as tapped, no matter which side they are on.

Existing solution:

get_chordal_hold() may be implemented for customization to compute as desired
