I am looking for a quick way to delete a line in netBeans.
For example in vim you can just type dd
for Deleting a line.
Does Ctrl-E not work for you? This is the default short-cut in NetBeans on a Windows machine.
If you click on Help you can get the keyboard shortcuts card, print it out, it's pretty handy and has saved me quite a bit of time hunting for easier ways to do things.
