All browsers also support BkSp and Shift+BkSp for backward and forward, and I think CN should support all common browser shortcuts for navigation. So we need to find something else for resetting the filters.

Yes, the point if the suggestion was to record keystrokes from ALL programs. But I doubt that it is worth it to turn CN into a keylogger, and according to the votes it seems that many CN users share this view ;)

Thanks for the comment, Devil ;) I reckon Ctrl+'+' and Ctrl+'-' will then also be supported.

I can't get my hands on "Microsoft Yahei".. Can you repeat the bug with a more common, international font, like Verdana or Tahoma? If not, could you please send me the TTF file? Thanks!

This is all very convincing, but frankly I'm still not 100% sure about the BkSp key.. if forward-backward navigation is implemented (and I intend to implement it eventually because I think this is a very organic feature), we will desperately need BkSp for "Back". Any ideas here?

Do you have this problem only with OneNote? Can you paste text from Word, Excel?

Thanks for the info!
