how to reset the font size in Editor

[ollydbg]

Hi, I'm using code::blocks svn on windows xp.
When I can use ctrl+ mouse scroll up and down to zoom in and out. But If I want to view the original size, How can I reset to the original size? Is their a short-cut? ( I have tested that even I close the whole project and reopen it again. the scintilla editor still remembers the custom view. )
Thanks.

No shortcut by default, but a menu-entry (a little bit hidden).

"Edit -> Special Commands -> Zoom -> Reset"

I assigned "Ctrl + 0" to the menu-entry on my system (using Keybinder-plugin).

Thank you for your help.
And, Keybinder plug-in == Keyboard shortcuts plug-in. (At first, I'm confused that there is a plugin named keybinder. But after opening the plug-in manager, I know it contains a "keybinder.dll", and they are the same one. )
