   Deletes the current line, which is one of my favorites, not to delete a row and press so many deletions.

5. "ctrl+m"

   window to maximize and restore, when the user in the window, always feel that the current window is small (especially when writing code), now good, try "ctrl+m" shortcut keys.

   View and locate shortcut keys

   In the program, quickly locate the location of the code, quickly find where the bug is a very difficult thing, Eclipse provides a powerful search function, you can use the following shortcut keys to help complete the job of locating.

   Find Workspace (Workspace) build path, not to find the class, and you can use "*", "? "And so on wildcard characters.

8. "Ctrl+shift+r"

   and "ctrl+shift+t" correspond to find all files (including Java files) in the workspace (Workspace), or you can use wildcard characters.

9. "Ctrl+shift+g"

   Navigates to a row in the current editor and is also valid for non-Java files.

4. "alt+←", "alt+→"

   Backward history and forward history are useful in tracking code, and users may find several associated places, but they may not be able to remember the order in which they are located by these two shortcut keys.

Ctrl+d: Delete When moving forward

Ctrl+alt+↓ Copy the current row to the next row (replication incremented)

Ctrl+alt+↑ Copy the current line to the previous row (replication incremented)
