why font in editor windows becomes so small?

[huzhongshan]

When I write code , the font  in editor window suddenly become very very small . Perhaps I pressed ctrl+??? something to trigger something on , but I cannot find how to go back.
I checked the settings->editor->font , it is Courier New ,size 10.

Hi,

see the manual http://www.codeblocks.org/docs/main_codeblocks_en.html in chapter "1.11.7  Zooming within the editor" for details.
