How to create context-sensitive hotkeys when no window is active? - windows

Question

I want to create some hotkeys when no window is active:
But there's no statement like #IfNoWinActive, how to achieve this?

Answer 1

There is always an active window (the one that will get input).
E.g. the Win+X Menu has no title but a hidden ahk_class (LauncherTipWnd). To detect it you have to add DetectHiddenWindows, On in your script:
#NoEnv
#SingleInstance Force
DetectHiddenWindows, On
#IfWinActive ahk_class LauncherTipWnd ; Win+X Menu
F1:: Run notepad
F2:: Send m ; starts the Device Manager
#IfWinActive
EDIT:
To get the title and ahk_class of the (hidden) active window, run this script and press F1 as soon as that window is active:
#NoEnv
#SingleInstance Force
DetectHiddenWindows, On
F1::
WinGetTitle, ActiveTitle, A
WinGetClass, ActiveClass, A
MsgBox, ActiveTitle: %ActiveTitle%`nActiveClass: ahk_class %ActiveClass%
return
F2::
WinSetTitle, A, , NewTitle
WinGetTitle, ActiveTitle, A
MsgBox, ActiveTitle: %ActiveTitle%
return
F3::
WinGet, ActiveExe, ProcessName, A
MsgBox, ProcessName: "%ActiveExe%"
return
Press Ctrl+C to copy the content of the MsgBox.
EDIT2:
In case the active window has no title and no ahk_class you can try this:
F1::
WinGetTitle, ActiveTitle, A
WinGetClass, ActiveClass, A
If (ActiveTitle = "" && ActiveClass = "")
Run notepad
; else If WinActive("WinTitle ahk_class WinClass", "WinText", "ExcludeTitlePart")
; do this
else
Send {F1}
Return

Answer 2

~Esc::
WinGet A, PID, A
if !A {
MsgBox ; 👈 put logic here
}
return
