Decouple mouse & keyboard focus

Question

I use windows 11, say i have two applications opened (for example browser that has video playing in it & notepad++), and each of the applications is displayed in separate monitor (i use dual monitors), so on one monitor I'm watching a video inside browser, and on another monitor I'm writing in notepad++ (taking notes from the video I'm watching) .

is there a way to have mouse focus kept in on the browser (so i could use mouse shortcuts to pause/resume/fast-forward/rewind the video) while maintaining keyboard focus on the notepad++ (so i can continue writing in notepad++ without the need to keep moving the cursor back to notepad++).

I think this can only be achieved by disabling cursor focus, that is keyboard focus following wherever my cursor clicks.

Not applicable, there is no such feature

Try this AutoHotkey script:

; Activate Notepad++ after using the mouse on Microsoft​ Edge or Chrome:

#Requires AutoHotkey v1.1

#If WinActive("ahk_class Chrome_WidgetWin_1") AND WinExist("ahk_class Notepad++")

    ~LButton Up::
    ~RButton Up::
    ~WheelUp::
    ~WheelDown::
        WinActivate, ahk_class Notepad++    
    return

#If

; Press F1 to disable or reenable the above hotkeys
F1:: Suspend

; Press Esc to terminate the script
Esc:: ExitApp
