- **evidence:** Ghidra /v2: op_0x10a_set_cursor_virtual@0x421590 maps virtual coordinates through the active VirtualFullScreen geometry and calls SetCursorPos. SC0000 alternates the cursor by one vertical pixel after state-changing ADV button clicks so the hover state re-enters cleanly.
### 0x12e `find-hit-rectangle` (find-hit-rectangle, argc 8)
- **summary:** (index_inout)(reference_rect)(pointer_x)(pointer_y)(rect_array)(x_offsets)(y_offsets)(count) - scan forward through encoded rectangles and return the next hit index, or -1.
- **summary:** (index_inout)(reference_rect)(pointer_x)(pointer_y)(rect_array)(x_offsets)(y_offsets)(count) - scan after the incoming index for the next inclusive rectangle intersection, or return -1.
- **grounding:** source=investigation, confidence=high
- **evidence:** Ghidra /v2: op_0x12e_find_hit_rectangle@0x428ff0 resolves the reference rectangle and three array operands as VM pointers, decodes rectangle/offset values with anti_tamper_a, scans candidates after the incoming index, applies per-entry x/y offsets to the pointer coordinates, performs rectangle overlap containment tests, and writes the matched array index or -1 to operand 1. HISTORY.BIN uses it for mouse hover selection over its literal-initialized row rectangles.
- **evidence:** Ghidra /v2: op_0x12e_find_hit_rectangle@0x428ff0 resolves the reference rectangle and three array operands as VM pointers, decodes rectangle/offset values with anti_tamper_a, and starts at incoming_index+1. Each candidate is [left,right,top,bottom]; the worker subtracts its per-entry x/y offsets from the pointer, inclusively intersects it with the reference rectangle, and writes the matched array index or -1 to operand 1. HISTORY.BIN uses decoded local arrays for scrollbar/control regions, close region 8, and visible text rows 9..13.
### 0x19a `get-message-skip` (u00414E50, argc 1)
- **summary:** (out) - return the current all-message skip state set by op 0x88.
