In my IntelliJ Idea 13.1.2 IDE I keep running into situations where I'm selecting on a click and drag via my laptop touch pad. I keep accidentally clicking and dragging text and cutting lines. I've searched the options and settings panels for the words click and drag but I don't see a way to turn this feature off. IntelliJ's help talks about how to use click and drag cutting but doesn't say how to disable it. Does anyone know how to disable cut and paste through click and drag in the IntelliJ IDE?
I found it in Settings → Editor → General.
Under the Mouse heading. The option is called "Enable Drag'n'Drop functionality in editor".
This also seems to disable drag and drop moving of files though.
There is no way to disable Drag-n-drop highlighted text in the editor itself!!! ALT guard for drag-n-drop files is a good idea as I accidentally drag and drop files on daily basis. Kudos for discovering that I just enabled it.
I have contacted Intellij support to give us a setting that we can disable in editor drag and drop. I think that is a stupid feature in the first place...
