Come rimappare Caps Lock + HKJL allo scroll del mouse usando Karabiner + Seil?

Ho rimappato Caps Lock in F19 in Seil.

In Karabiner, ho rimappato F19 in Hyper .

<item>
    <name>CAPS to HYPER</name>
    <appendix>Caps to Hyper</appendix>
    <identifier>private.caps_to_hyper</identifier>
    <autogen>__KeyToKey__ KeyCode::F19,  ModifierFlag::OPTION_R | ModifierFlag::SHIFT_R | ModifierFlag::COMMAND_R</autogen>
    <autogen>__KeyToKey__ KeyCode::F19,  ModifierFlag::OPTION_R | ModifierFlag::SHIFT_R | ModifierFlag::COMMAND_R</autogen>
    <autogen>__KeyToKey__ KeyCode::F19,  ModifierFlag::OPTION_R | ModifierFlag::SHIFT_R | ModifierFlag::COMMAND_R</autogen>
    <autogen>__KeyToKey__ KeyCode::F19,  ModifierFlag::OPTION_R | ModifierFlag::SHIFT_R | ModifierFlag::COMMAND_R</autogen>

Ora, sto cercando di ottenere Hyper rimappato come scroll del mouse quando usato con H J K L .

<item>
    <name>Scroll</name>
    <identifier>private.scroll_keys</identifier>
    <autogen>__KeyToKey__ KeyCode::F19, KeyCode::H,  KeyCode::VK_MOUSEKEY_SCROLL_LEFT</autogen>
    <autogen>__KeyToKey__ KeyCode::F19, KeyCode::J,  KeyCode::VK_MOUSEKEY_SCROLL_DOWN</autogen>
    <autogen>__KeyToKey__ KeyCode::F19, KeyCode::K,  KeyCode::VK_MOUSEKEY_SCROLL_UP</autogen>
    <autogen>__KeyToKey__ KeyCode::F19, KeyCode::L,  KeyCode::VK_MOUSEKEY_SCROLL_RIGHT</autogen>
</item>

Qualche idea su cosa sto facendo male?

(Per riferimento, ho anche il seguente nel mio file private.xml per fare Control - H J K L tasti freccia)

<item>
    <name>HJKL Cursors</name>
    <appendix>This uses HJKL to browse System Wide (Left/Down/Up/Right)</appendix>
    <identifier>private.change_browse_to_hjkl</identifier>
    <autogen>__KeyToKey__ KeyCode::H, ModifierFlag::CONTROL_L, KeyCode::CURSOR_LEFT</autogen>
    <autogen>__KeyToKey__ KeyCode::J, ModifierFlag::CONTROL_L, KeyCode::CURSOR_DOWN</autogen>
    <autogen>__KeyToKey__ KeyCode::K, ModifierFlag::CONTROL_L, KeyCode::CURSOR_UP</autogen>
    <autogen>__KeyToKey__ KeyCode::L, ModifierFlag::CONTROL_L, KeyCode::CURSOR_RIGHT</autogen>
