Require BT_CLR held for X seconds before triggering?
What I want: To have to hold my
&bt BT_CLR key for 5 seconds before the clear occurs. I want to avoid accidentally resetting bluetooth pairing
I can't seem to figure out how to do that reading the ZMK docs and/or asking other LLMs. Hoping the TyperAI bot or someone else might be able to point me in the right direction?2 Replies
Yep — you can gate BT_CLR behind a long hold using ZMK’s Hold-Tap behavior. Make a custom hold-tap that:
- tap = does nothing
- hold = runs BT_CLR
- tapping-term-ms = 5000 (5 seconds)
Example devicetree overlay snippet:
- Define the behavior
/ {
behaviors {
bt_clr_hold_5s: bt_clr_hold_5s {
compatible = "zmk,behavior-hold-tap";
label = "BT_CLR_HOLD_5S";
tapping-term-ms = <5000>;
quick-tap-ms = <0>;
flavor = "balanced";
/* hold, then tap */
bindings = <&bt BT_CLR>, <&none>;
};
};
};
- Use it in your keymap in place of &bt BT_CLR:
bindings = <&bt_clr_hold_5s>, …;
This makes quick presses do nothing, and only triggers the clear once you’ve held the key for 5 seconds.
Docs for reference: Hold-Tap behavior
Alternative: If you’d rather require a “confirm” chord instead of a long hold, you can move BT_CLR behind a combo so it only fires when two positions are pressed together: Combos
If you want, reply or tag me with your keymap overlay and I’ll sanity-check the snippet or tailor it to your layout.
The above was close.
