When I use Eclipse (Neon3), I have encountered the problem of some shortcut keys failing:
For example, Ctrl+D (delete the current line), Ctrl+Alt+↓ are often used, but the shortcut keys that are not unique to Eclipse can still be used to copy and paste.
I searched a lot of solutions on the Internet, such as modifying the shortcut keys in preferences, but they are not easy to use. Finally found that as long as the open window is closed, and then open the shortcut key, it is all easy to use.
This method is very simple, and my problem is solved in this way. Send out to help people who are also troubled.
