Inadvertent zoom out for a single file

[dnewhous]

For a single file I inadvertently changed the display so that the font has seamed to shrink.  It is not a font size change, because if I change the font size the display changes for all files. Is there way I can set the file's display back to default?

Ctr+mouse scroll or Edit->Special commands->Zoom->Reset

There is an option to make the zoom be the same for all editors or only for the active editor, search the options for details.
