IntelliJ IDEA way of editing multiple lines

Question

I've seen this done in TextMate and I was wondering if there's a way to do it in IDEA.

Say I have the following code:

 leaseLabel = "Lease";
 leaseLabelPlural = "Leases";
 portfolioLabel = "Portfolio";
 portfolioLabelPlural = "Portfolios";
 buildingLabel = "Building";

What is the best way to append '+ "foo"' to every line? Column mode won't work since the lines are not correctly aligned on the right side... unless there is an easy way to right justify the text :P

Answer 1

In this case you can also just select the piece of code in which you want to do this and perform a replace on it. Replace:

";

with:

" + "foo";

So in case you didn't know: If you have text selected while you perform a replace (Ctrl+R or Cmd+R) it will only apply to the selected piece of text.

Answer 2

Place caret at end

Windows: CTRL + CTRL(Hold) + ↑ / ↓

Mac: option + option(Hold) + ↑ / ↓.

To place caret at the end of rows: move caret to top row, clone down to bottom, and click END.

Change Multi-caret Hotkey

To add a custom Keymap, CTRL+SHIFT+A, type keymap and click on the one with Settings as subtext. Search for Clone Caret Above and Clone Caret Below.

I mapped mine to ALT+SHIFT+↑ / ↓ on Windows and ⌘+↑ / ↓ on Mac.

Bonus

Try holding combinations of CTRL, SHIFT, and arrows for improved selection power.

Select Next Occurrence:

      Alt+Shift+J on Windows, Ctrl-Shift-G on Mac OS X

Select All Occurrences:

      Ctrl+Alt+Shift+J on Windows, Ctrl-Cmd-G on Mac OS X

Answer 6

It took me a while to find out, but on a Mac you can double-press Option (press it once, release, press it again, keep it pressed) and use Up/Down keys to create/remove carets as you wish.

You can also hold Shift+Option and click to create/remove carets at specific points.
