These Quick Drop Keyboard Shortcuts - created by LabVIEW Champion Dany Allard - do exactly what their names suggest: They offer the same beaviour as the original Replace and Insert shortcuts, but add the capability to replace with / insert an object from the clipboard. You can configure them to use the original shorcuts ctrl-P and ctrl-I.
You can download the VIs from NI's Quickdrop Enthusiasts Group:
- Replace from Clipboard
- Insert from Clipboard
And if you cannot remember how to install Quickdrop keyboard shortcuts, the answer - as so often - is to go to Darren's blog and read his blog post on Getting Started with QD Keyboard Shortcuts.
