[Solved] How Can I invoke Fn Shorkeys (adjust Brightness)?

[bester69]

Hi,

I need to adjust brightness and sound from my USB keyboard that is missing those Fn keys.. so I would need something like this..:

Ctrl+ LeftCursor (xdoot script Plama Shortcut)--> Maps: Fn+8 (brigntness Up keys on laptop keyboard)
Ctrl+ RightCursor (xdoot script Plama Shortcut)--> Maps: Fn+7 (brigntness Down keys on laptop keyboard)
Ctrl+ UpCursor (xdoot script Plama Shortcut)--> Maps: Fn+6 (Volume Up keys on laptop keyboard)
Ctrl+ UpCursor (xdoot script Plama Shortcut)--> Maps: Fn+5 (Volume Down keys on laptop keyboard)
xdotool <<Laptop Keyboard>> key <<ctrl+q>>

I think to have readen somewhere xdotool cant use Fn buttons.. anyway.. is there an easy way to achieve this ..It doesnt seem easy task



Thanks

Volume Up:
qdbus org.kde.kglobalaccel /component/kmix invokeShortcut "increase_volume"
Volume Down:
qdbus org.kde.kglobalaccel /component/kmix invokeShortcut "decrease_volume"
Volume Mute:
qdbus org.kde.kglobalaccel /component/kmix invokeShortcut "mute"

Brightness Up:
qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement/Actions/BrightnessControl org.kde.Solid.PowerManagement.Actions.BrightnessControl.setBrightness $(expr $(qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement/Actions/BrightnessControl org.kde.Solid.PowerManagement.Actions.BrightnessControl.brightness) + 20)
Brightness Down:
qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement/Actions/BrightnessControl org.kde.Solid.PowerManagement.Actions.BrightnessControl.setBrightness $(expr $(qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement/Actions/BrightnessControl org.kde.Solid.PowerManagement.Actions.BrightnessControl.brightness) - 20)


Thanks.
