Quick Drop in LabVIEW

Time is one important factor during certification exams. You need to look into various techniques that can effectively improve your programming speed. One such technique in my opinion is the use of Quick Drop Dialog Box. Introduced from LabVIEW 8.6, it allows you to directly drop the objects from the palette without having to navigate through the various levels of the palette.

Access the Quick Drop Dialog Box by either of the following methods,

  • Press <ctrl-space> from the keyboard
  • Go to menu, select  View>>Quick Drop

Enter the name of the object you are looking for in the search box, to obtain the list of possibilities as seen below. Select the object and press ENTER to drop it on the block diagram.
