Ctrl + Shift + U

In the future try typing: Ctrl + Shift + A and look for any actions you like. Here: Toggle Case.

Or ⌘ Command + Shift + U if you are using Mac OSX.

In case it helps someone who wanders in here: In Eclipse, this is CMD+SHFT+Y (lower) and CMD+SHIFT+X (upper) – gMale Aug 01 '13 at 07:53

I have trouble where sometimes pressing CTRL+SHIFT+U just replaces the selected text with the letter U.... sometimes it works, but usually it just does the replacing. – Trenton Jul 31 '14 at 16:15

@Trenton - if you're using Ubuntu CTRL+SHIFT+U by default is used for Unicode input thus you're seeing the letter u. If you don't use it you should probably unbind it (looks like it's not so easy http://askubuntu.com/questions/367646/is-it-possible-to-unbind-or-change-the-unicode-input-global-shortcut) or define a new shortcut for this action in Intellijf – Kuba Dec 11 '14 at 11:35

`export XMODIFIERS="" ./bin/idea.sh` solves to me, using Ubuntu. – deFreitas Jul 26 '18 at 22:46

@Kuba in October 2018 I can confirm that Debian does this too – sox supports the mods Oct 10 '18 at 17:32

Obsolete, do not toggle any more. It will only make characters upper case. – Jan Seevers Jul 17 '17 at 09:36

I would highly recommend String Manipulation plugin for Intellij.

With a simple Alt + M (Option + M for Mac) you get:

So you can easily manipulate with strings in the following way:

If you are an Ubuntu User you will notice that Ctrl + Shift + U will add an u instead of toggling the case.

The solution for me was to change the KeyMap from:

Ctrl + Shift + U --> Alt + Shift + U

You can do so with this Docs

There's an alternative way, supressing `Ctrl + Shift + U` handling by Ubuntu, so IntelliJ Idea works as usual https://superuser.com/questions/358749/how-to-disable-ctrlshiftu – edwgiz Sep 28 '22 at 09:23

Select the text/word/line to be modified and hitting Cntrl+Shift+U or Command+Shift+U` (MAC) works. Please look here for more detail

Any specific reason it is down voted? I just verified in IntelliJ and confirmed this – Shravan Ramamurthy Aug 24 '17 at 21:03
Had to convert a project from MSSQL (Pascal case) to Postgres (lowercase). This saved me a ton of time! – cbmeeks Jun 22 '22 at 14:57

Please check your hot-key settings first. You could go to

File > Settings > Search for Keymap > Search for Toggle Case

and see what hot-key has been configured. See screenshot below:-

If not configured, create a new one for yourself.

Toggle case in Intellij IDE:

For Ubuntu OS use Ctrl+Shift+x or Ctrl+Shift+y

For Windows OS use Ctrl+Shift+u
