Sometimes it is all about knowing the simple tricks in Eclipse which make life easier. Like this one: how to have a split editor view so I can edit multiple different sections of a source file:

That feature is present in Eclipse Luna and afterwards, but because there is no icon in the view itself as in Microsoft Word, I have found that many do not know about this useful feature. The screensthots below are for Eclipse Luna.

Split Editor View

To split an editor view, I have it selected (to be active), then I use the menu ‘Toggle Split Editor’:

I can split it horizontal:

Or in a vertical way:

I can use the mouse to resize the split area:

To remove the split, simply use the menu or shortcut again:

Clone Editor View

The other useful function is to clone an Editor view:

This creates a clone of that view:

To ‘undo’ the cloning, I close the new editor view.

Summary

Splitting and Cloning gives me a way to edit the same source file in different portions of that file. The commands to Clone and Split is under the Window > Editor menu.

Happy Cloning & Splitting 🙂
