I tried to make a hack to workaround such keys, but didn't succeed. So I need Steven's help to intercept some common keys such as space or enter assigned as hotkeys.
That's okay, I just took out that hotkey. Didn't use it much anyway.
Since then, I've made a bit of a mess and I'm not sure how to fix it. I was trying to copy the Writer tag (from Musicbrainz) into the Composer tag.
First, somehow I ran the copy without meaning to - I was just trying to check/uncheck specific files.
Second (or maybe this should be first), the reason I was fiddling with which files to apply it to was because it wasn't handling the "append to" command well, even though I had "smart copy" option selected. If I told it to append with ; as a separator, it wanted to put ; even in tags that should be blank. If I told it not to use a separator, then when there was a value in both Writer and Composer it mushed them together.
And somehow the tags where Writer had multiple values got copied as a single value. As soon as I go into the file and open the Composer split screen, it sorts them out correctly without my doing anything. But until I do that, I have values showing up in Library Explorer like "Andy SelwayJules Hodgson; Sascha Konietzko; Lucia Cifarelli; Andy Selway". Which somehow fail to make the associated tracks appear in the main window, even though they show up in Library Explorer...
Can you offer any advice in sorting this out? I hope it can be solved without editing every single file by hand...
