feat(pointing): add pointing modes (Cursor/Scroll/Sniper) by Schievel1 · Pull Request #874 · HaoboGu/rmk

Schievel1 · 2026-06-04T05:28:32Z

Summary

Thanks to Raymond8196 for most of the work on this. See also #728
Add pointing device modes to RMK, allowing trackballs to behave differently on different modes (e.g., scroll on layer 1, precision mode on layer 2).

Key Features

Per-Layer Pointing Modes:

Cursor: Normal trackball mode (default)
Scroll: Convert motion to scroll wheel events
Sniper: Reduced sensitivity for precision control
Caret: Emit keytaps with trackball movement (mostly arrow keys, but can be configured)

Usage:

use rmk::{
  event::{LayerChangeEvent, PointingProcessorEvent, publish_event},
  input_device::pointing::PointingMode, types::keycode::HidKeyCode,
};
use rmk_macro::processor;

#[processor(subscribe = [LayerChangeEvent])]
#[derive(Default)]
pub struct PointingProcessorController;

impl PointingProcessorController {
  pub fn new() -> Self {
      Self
  }

  async fn on_layer_change_event(&mut self, event: LayerChangeEvent) {
      match event.0 {
          0 => {
              publish_event(PointingProcessorEvent {
                  device_id: 255,
                  mode: PointingMode::Cursor,
              });
          }
          1 => {
              publish_event(PointingProcessorEvent {
                  device_id: 255,
                  mode: PointingMode::Sniper(rmk::input_device::pointing::SniperConfig {
                      divisor: 8,
                      invert_x: false,
                      invert_y: false,
                  }),
              });
          }
          2 => {
              publish_event(PointingProcessorEvent {
                  device_id: 255,
                  mode: PointingMode::Scroll(rmk::input_device::pointing::ScrollConfig {
                      divisor_x: 16,
                      divisor_y: 16,
                      invert_x: false,
                      invert_y: false,
                  }),
              });
          }
          3 => {
              publish_event(PointingProcessorEvent {
                  device_id: 255,
                  mode: PointingMode::Caret(rmk::input_device::pointing::CaretConfig {
                      disable_x: false,
                      disable_y: false,
                      invert_x: false,
                      invert_y: false,
                      threshold: 100,
                      keycode_up: HidKeyCode::Up,
                      keycode_down: HidKeyCode::Down,
                      keycode_left: HidKeyCode::Left,
                      keycode_right: HidKeyCode::Right,
                  }),
              });
          }

          _ => {}
      }
  }
}

Technical Details:

Sub-pixel motion accumulation prevents precision loss
Configurable sensitivity divisors for each mode
Memory overhead: ~17 bytes (4-layer keyboard)
Backward compatible: default behavior unchanged

Test Plan

unit tests for mode switching, accumulation, and edge cases
All existing tests pass, zero clippy warnings
Tested with PMW33xx/PMW3610 examples
Verified Vial compatibility

docs for toml configuration
Docs on caret mode
Tests for caret mode
Make caret mode less jittery (although maybe thats just my sensor)
integration mode? (https://codeberg.org/Schievel/dactyl_manuform_r_track#headline-26) -> no

Add support for pointing device modes to PointingProcessor. Users can now configure different layers to have different trackball behaviors, enabling scroll and precision modes via event based switching. Changes: - Add PointingMode enum (Cursor/Scroll/Sniper) with configs - Add MotionAccumulator for sub-pixel delta tracking - Subscribe to PointingDeviceEvent to receive layer changes Backward compatible: default behavior unchanged Addresses HaoboGu#703 Co-authored-by: Pascal Jäger <pascal.jaeger@leimstift.de> Signed-off-by: Pascal Jäger <pascal.jaeger@leimstift.de>

alrighty. Test fail, I will take care of this later.

In qmk I used to have integration scrolling mode. When in this mode, the trackball not just acts like a scroll wheel, but instead when you move it in one direction, and leave it there, it keeps scrolling. (even though the trackball is not rolled anymore)
I never got the hang of it, but some people found it extremely useful for having autoscroll in programs that do not automatically support it. They set up a PDF, activate this slow scroll in their reading pace and start reading.
Shall we implement that as well?

Also there's caret mode, which basically emits arrow keys when moving the trackball. Useful to move the cursor in text documents.

More info on those:

alrighty. Test fail, I will take care of this later.

In qmk I used to have integration scrolling mode. When in this mode, the trackball not just acts like a scroll wheel, but instead when you move it in one direction, and leave it there, it keeps scrolling. (even though the trackball is not rolled anymore) I never got the hang of it, but some people found it extremely useful for having autoscroll in programs that do not automatically support it. They set up a PDF, activate this slow scroll in their reading pace and start reading. Shall we implement that as well?

Also there's caret mode, which basically emits arrow keys when moving the trackball. Useful to move the cursor in text documents.

More info on those: https://codeberg.org/Schievel/dactyl_manuform_r_track#headline-26

I looked into this, and caret makes sense to implement. But integration mode is a thing that kind of just falls into place for QMK, because of the way QMK does things with polling and mouse reports.
But for event based RMK it is way too complicated to implement for such a seldom used feature. Therefore I dropped the idea. If someone needs integration mode, they can do their own PointingProcessor and use that.
