In Microsoft Office 2007 you can use the Change Case button on the Home tab.

Change case button

If that is not what you are looking for you will need to add more details to your question.

Or press Shift+F3. – Joey Feb 24 '10 at 0:51
@Johannes Rössel Shift+F3 is a nice quick way to cycle through the casing options. – Nick Josevski Feb 24 '10 at 1:37
Very odd having a button that changes the text mixed up with formating that just changes the look of the text. – Ian Ringrose Feb 2 '14 at 11:47

When you've had caps lock on by mistake, highlight the words you typed and press Shift+F3. Pressing Shift+F3 repeatedly swaps between upper case, title case and lower case.

eg. if you type:


... then select all the text and press Shift+F3:


... then press Shift+F3 again:


... and Shift+F3 again:

this is a test.

... and Shift+F3 one last time:

This is a test.

It's interesting that the behaviour is a little different if there is no full stop (period character) in the selected text. Shift+F3 then capitalizes every word when switching to title case:

This Is A Test

Hope this helps.

As for the funny difference with the trailing dot: when applying styles in Word, Word is also aware of what is selected. Things like bold and italic are preserved if less than 50% of the text is formatted in bold or italic. If 50% or more uses that formatting, then applying a new paragraph style removes that character formatting on the fly... (Nice answer; welcome at Super User!) – Arjan Feb 24 '10 at 13:09
Pressing Shift+F3 toggles between capitalizing all the letters in the selected text and capitalizing only the first letter of each word. This happens whether the sentence ends in a full stop/period or not. [At least this is what I experienced when I tried it myself.] – Isxek Feb 24 '10 at 13:38
Arjan, that's a funny thing about bold or italic, I hadn't noticed that! Thanks for your warm welcome, I've only been here a couple days so far. – Matthew Eyles Feb 25 '10 at 11:30
Is there a mac version? function/shift/command f3 all don't work. – MarcusJ May 23 '14 at 6:59

Hold Shift when typing?

Shift+F3 does not work for some strings, like


If you highlight that then hit Shift+F3, nothing happens. You have to either use the Change Case button as shown above or add an extra word, like

Then Shift+F3 will cycle through the capitalization options.

If you have a few minutes, write "3D" into Word, highlight it, then hit Shift+F3 a few times. Why do you think this feature was implemented in this manner?

The only thing I know about 3D for the quoted printable characters is the =3D is the encoded form of '=', i.e. similar to &. But for those of us without Word could you let us know what it does do? – icc97 Sep 11 '14 at 12:11

Ctrl + Shift + A
