Split window with shortcut key

Question

Is there any shortcut to split editor window in eclipse? Or can I set this?

Answer 1

Those shortcuts will exist soon (4.4 M4+), as announced by Lars Vogel (December 2013) in "Split editor implemented in Eclipse Luna 4.4 M4 Luna":

(4.4 M4+) shortcut for splitting is:

• Ctrl + _ for split horizontally, and
• Ctrl + { for split vertically.

4.4 final (update October 2014)

Szorstki reports in the comments:

• Ctrl + Shift + _
• Ctrl + Shift + {

Worked in my Eclipse Luna

As commented below by Tobias Lott, there is still a pending bug (438562) regarding keyboard layouts, e.g. German, Swiss German or Italian.

Answer 2

Nope this is one of the oldest outstanding enhancement requests in Eclipse. As noted in the last comment, it will be 10 years old next month.
