Solution
Quick Drop is a function provided in LabVIEW 8.6 version or later. This function is used to find the item in the Front Panel and Block Diagram rapidly without searching on the Functions Palette Controls Palette or Global search.
To use Quick Drop function, press
Ctrl + Space and the list will show all available VI. A user can select the VI needed and place on the Block Diagram.
However, Ctrl + Space has already been used as a shortcut in Windows to switch input language in some localized OS(Operating System) such as Traditional Chinese (Taiwan). If pressing Ctrl + Space, the Windows system will switch input language but not open the Quick Drop.
As a result, to use the Quick Drop through a shortcut in these OS, you need to change the shortcut of the Quick Drop by selecting
Tools >> Options in LabVIEW and select
Quick Drop in
Menu Shortcuts tab. Then, change to preferred shortcut, like Ctrl + Shift + Space, so that user can use new shortcut to call Quick Drop.
