By accident I discovered something in SQL Developer. Another one of those things I need to remember for future reference. Hope you can use this feature too.
You know you can use CTRL + C for copying and CTRL + V for pasting. Nothing new there, but what is really neat is that you can use SHIFT + CTRL + V to see the contents of all your clipboard items.
Because I needed to do a lot of copying today, this came in really handy.
