Thanks for helping! I'm afraid there is an error in the manual. It says:
To replace every occurence of a glyph in all visible unlocked layers of an image, Ctrl-LMB on it in the font window, then Ctrl-LMB on the new glyph to replace it with. After selecting a source glyph, the swap can be cancelled by again pressing Ctrl-LMB on the same glyph.
Ah yeah, sorry that's the old version you have. This was fixed and other features have been added or addressed in newer patches available here on the forums, but I haven't done a public release on the site in quite some time since I generally like to wait until there is a larger number of new features available for that. Still, I should probably do that to avoid getting reports of things that don't match up with the current version
(In the version you have, the shortcut is correct in the full command list, but not in the full text of the manual, where I had forgotten to change it at the time.)
Also it'd be cool if the download page said that ANSI version comes with non-square fonts and normal version doesn't.
Hm, true, could be helpful for some
I'd much prefer if both included all versions, but this makes it harder for newer users.
