The bindings dropped every mouse button while the cursor was not captured, and the menu pointer releases the capture, so side buttons bound to L and R turned the menu's tabs only in the frames before the pointer appeared. While the menu pointer is shown and over the window, the middle and side buttons now count; the left and right buttons stay the menu's A and B. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

// Host input for nn::hid (runtime/ov_input.c): an SDL3 gamepad (no SDL window needed), the keyboard and the mouse,
|
|
// merged into Switch npad button bits and stick axes. Button order follows libnx HidNpadButton (ISC). The key and pad
|
|
// bindings are the tables in input_map.c (totk.ini overrides them). The keyboard and the mouse come from the window
|
|
// system's back end (input_wsys.h: input_win.c with Win32, input_sdl.c with SDL), which also owns the cursor capture.
|
|
// Keys and their map: docs/controls.md.
|
|
// The gamepad also rumbles (input_rumble) and, when it has a gyro and an accelerometer, feeds the six-axis sensor from a
|
|
// thread of its own (input_motion_start). Every SDL call on the gamepad is made under `lock`.
