Want to send hotkey as F8 with Fn

there is no Key modifier as Fn. Help me to resolve this. thanks in advance…

The Fn key is a special key controlled by hardware. It’s not a key you can simulate via software. What does Fn+F8 do on your computer?

Fn+F8 will popup a LOV field

It seems like you just need to simulate a regular F8 key. On an HP laptop, for example, mute microphone and F8 is on the same key. Pressing that key would mute the mic while pressing Fn+F8 would give you a regular F8 key press.

Have you tested to use the Send Hotkey activity to send just the F8 key?
