Sorry, just found solution after reading Karabiner Docs. Solution is export config with:
Open config folder from Preferences > Misc. Copy the karabiner.json file. Then replace this code:
{
"description": "SpaceFN: Space+u to Home, Space+o to End",
"manipulators": [
{
"conditions": [
{
"name": "spacefn_mode",
"type": "variable_if",
"value": 1
}
],
"from": {
"key_code": "u",
"modifiers": {
"optional": [
"any"
]
}
},
"to": [
{
"key_code": "home"
}
],
"type": "basic"
},
{
"conditions": [
{
"name": "spacefn_mode",
"type": "variable_if",
"value": 1
}
],
"from": {
"key_code": "o",
"modifiers": {
"optional": [
"any"
]
}
},
"to": [
{
"key_code": "end"
}
],
"type": "basic"
}
]
},
{
"description": "SpaceFN: Space+h to Page Up, Space+n to Page Down",
"manipulators": [
{
"conditions": [
{
"name": "spacefn_mode",
"type": "variable_if",
"value": 1
}
],
"from": {
"key_code": "h",
"modifiers": {
"optional": [
"any"
]
}
},
"to": [
{
"key_code": "page_up"
}
],
"type": "basic"
},
{
"conditions": [
{
"name": "spacefn_mode",
"type": "variable_if",
"value": 1
}
],
"from": {
"key_code": "n",
"modifiers": {
"optional": [
"any"
]
}
},
"to": [
{
"key_code": "page_down"
}
],
"type": "basic"
}
]
},
to this:
{
"description": "SpaceFN: Space+u to Page Up, Space+o to Page Down",
"manipulators": [
{
"conditions": [
{
"name": "spacefn_mode",
"type": "variable_if",

}
},

}
]
},
{
