How to do multiple line editing? - eclipse

Question

I want to edit multiple lines in eclipse, but I can't find any short cut or Plugin. In Geany I just press ctrl+alt+up/down I can add / edit multiple lines.
Maybe this example can explain what I mean:
var text = "myname";
var addr = "myaddr";
var age = "myage";
I want to edit text above into:
var my_text = "myname";
var my_addr = "myaddr";
var my_age = "myage";
The text above is just a simple example, but sometimes I have many lines of words that I have to edit its prefix.

Answer 1

Press alt + shift + A to Toggle block selection (Toggle block / column selection in the current text editor), this will let you write vertically in eclipse, then you can easily do this.
Go to Window->Preferences.
Find for binding in text box surrounded by red box.

Answer 2

On OS X, the key combination for multi-line edits in Eclipse (or STS) is option/alt+command+A

Answer 3

You can try the following plugin,
https://github.com/caspark/eclipse-multicursor/releases
With this multiple occurrence of same text can be selected and edited. This is similar to multi select functionality available in editors like Sublime and Visual studio code.

Answer 4

The Eclipse 4.24 (June 15 2022) will integrate it (See https://bugs.eclipse.org/bugs/show_bug.cgi?id=576377):
Multi selection down relative to anchor selection (e.g. Ctrl-Alt-J)
Multi selection up relative to anchor selection (e.g. Alt-J)
End multi-selection (e.g. ESC)
Add all matches to multi-selection (e.g. Ctrl-Shift-Alt-J)
Multi caret up (e.g. Ctrl-Alt-Shift-Up)
Multi caret down (e.g. Ctrl-Alt-Shift-Down)

Answer 5

The Eclipse 4.22 (Q4 2021) equivalent of Geany would Alt+Click on the lines you want to edit in one go.
Eclipse now supports
Multiple text selection
Support for multiple selection has been added to Text Editors.
Multi selections allow most edit operations (text replacement or insertion, extend selection to next word or to next line, copy/paste...) to apply simultaneously on all ranges.
Multiple strategies are available to enable multi-selections:
Turn a block selection into a multi-selection using the To multi-selection command,
Add a caret with Alt+Click,
Use the new Select All button on the Find/Replace dialog.
So check if this would work in your case.

Answer 6

I know this is an old post, but I still want to share my way of multi select and editing. However this way is restricted to only the same variables across the file. Simply highlight the variable to edit, right click, choose Refactor->Rename. Then edit the variable and it will also edit the same variables across the file. Hope it helps..:)
