Hi,
I am unable to get the forward slash, /, to work as a macro for “fit to window”. Is it a bug or is there a special procedure. The other shortcut A, F. N work fine.
Regards

It is working fine for me. Forward slash is listed in the shortcuts for the glyph edit window.
Are you using a standard UK keyboard. Which version of FontCreator are you using, and on which OS?
Confirmed. Currently this short-cut only works on specific keyboards. This will be fixed as soon as we release a new version.
