Ctrl + Shift + U

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

In the future, hit the Ctrl + Shift + A shortcut key and search for the action that you are after. In this case, search for: Toggle Case.

    In case it helps someone who wanders in here: In Eclipse, this is CMD+SHFT+Y (lower) and CMD+SHIFT+X (upper)

    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 - 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 askubuntu.com/questions/367646/…) or define a new shortcut for this action in Intellijf

    @Kuba in October 2018 I can confirm that Debian does this too

According to the documentation :

Ctrl + Shift + U : Toggle case of the selected text block

    Obsolete, do not toggle any more. It will only make characters upper case.

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

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.

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
