## Key Down

`client.computers.keyDown(stringid, ComputerKeyDownParamsbody, RequestOptionsoptions?): ActionResult`

**post** `/computers/{id}/key-down`

Press and hold a keyboard key. Use with key_up to release. Supports modifier keys (shift, ctrl, alt, meta) for complex interactions like Shift+Click.

**Supported keys:** Modifier keys (shift, ctrl, alt, meta), special keys (enter, escape, tab, backspace, delete, space), arrow keys (arrowup, arrowdown, arrowleft, arrowright), navigation (home, end, pageup, pagedown), function keys (f1-f24), and any single character (a-z, 0-9).

**Key names are case-insensitive:** "shift", "Shift", and "SHIFT" all work.

**Example Shift+Click:** 1) key_down "shift", 2) click at coordinates, 3) key_up "shift"
