Is it possible to assign an owner to a Toolbar started from a key trigger

[Kevin]

it's certainly possible if i understand you correctly

a couple examples
#1
toolbar is attached to whatever window is active when Ctrl+F1 is pressed

Trigger CF1     

Code:

Copy      Help

int hwnd = win()
mac "ToolBar1" hwnd

#2
this one waits till you left click a window after pressing Ctrl+F1

Trigger CF1     

Code:

Copy      Help

OnScreenDisplay "Move mouse to desired window and left click to attach toolbar to it" -1 0 0 "" 0 0 8
wait 0 ML
int hwnd = win(mouse)
mac "ToolBar1" hwnd
