I have recently started using Intellij and I noticed that by default, when you do ctrl+c for copying something when you have nothing selected, it copies the entire line into the clipboard overriding what I had in there before.
This is really annoying yet I cannot seem to figure out how to disable it. I am aware that there is a paste history you can use however this is not what I am after, I just want to disable it like you can do with sublime text.
Is there a way to disable this behaviour so that when I press ctrl+c and nothing is selected it just leaves the clipboard alone?
Invoke Help | Find Action... (Ctrl (Cmd on Mac)+Shift+A), type Registry and select the Registry... item that appears. Enable the editor.skip.copy.and.cut.for.empty.selection option there. Be careful with the other configuration options, because it is possible to break your IntelliJ IDEA installation with an incorrect setting.
In Mac OS X:
- Press cmd+shift+a.
- Type
registryand press return to open the Registry. - Enable the
editor.skip.copy.and.cut.for.empty.selectionoption. - Click Close.
