Hi,

 

Is it possible to detect if the CTRL or SHIFT key is being held down when an application starts?

You can query the state of these buttons using https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getkeystate


if GetKeyState(VK_CONTROL)<0 then

  ....

 

  if GetKeyState(VK_SHIFT)<0 then
    ....

Use GetAsyncKeyState instead of GetKeyState.

 

GetKeyState will get you the state of the keys when a message was last read from the Windows message queue. This may or may not correspond to the current keyboard state.

GetAsyncKeyState will get you the current state.
