name: click
description:
Click against a target pid. **Prefer `element_index` over pixel coordinates** — element_index works on backgrounded / hidden windows, surfaces a stable handle, and tells you what you're clicking via the cached AT-SPI element's role + label. Reach for `x, y` only when the target is a canvas / custom-drawn surface that doesn't appear in the AT-SPI tree.
Provide either (window_id + x/y) or (pid + element_index). Routes via XSendEvent (no focus steal). element_index cache is scoped per (pid, window_id) and is replaced by the next get_window_state of the same window — re-snapshot every turn before clicking.
After a zoom call, pass from_zoom=true to auto-translate zoom-image coords back to full-window space.
button: "left" (default), "right", or "middle". Defaults to left so the field is fully back-compat. X11: routes through XSendEvent ButtonPress/Release with the matching button code. Native Wayland: only left-button is supported via the virtual-pointer protocol — right/middle return an error rather than silently degrading to left. `modifier` holds ctrl/shift/alt/super for the click on X11. Native Wayland refuses modified pointer clicks until its input protocol can carry keyboard modifier state.

'foreground' is the explicit escalation: activate the target (X11 _NET_ACTIVE_WINDOW; Wayland compositor activate), inject, then restore the prior active window — a brief focus swap unless the target was already active.
