Feature request: antecedent-morph (aka adaptive keys)
urob opened this issue · comments
This is an idea for a new behavior, which I think could be really useful and open up all sorts of creative uses:
The antecedent-morph
behavior would trigger an alternative binding if within timeout-ms
the immediate predecessor matches the trigger condition. This would enable using adaptive keys where certain keys change their meaning if pressed immediately after another key, as popularized by the Hands Down layouts.
For instance, in the Hands Down layout, ,A
send UA
. Using the proposed behavior, this could be implemented by replacing &kp A
with a antecedent-morph
configured as follows:
adaptive_A: adaptive_A {
compatible= "zmk,behavior-antecedent-morph";
bindings = <&kp A>, <&morphed_A>;
timeout-ms = <1000>;
antecedent = <&kp DOT>:
}
and where &morphed_A
is a macro executing BACKSPACE
, U
, A
.
Would be fixed by #2042.
