I understand how you feel about it, the reason is that CintaNotes from the beginning was heavily text-oriented and to gain competitive edge we continued to improve it in this direction and added tag hierarchy and autotagging rules. For richly formatted notes with images there's always been Evernote and Onenote, and we thought that to survive we must do something different.

However we do realise how important this is, and still plan to implement it.

It does a similar, but different thing: it clears contents of the search box when you press Ctrl+F to focus it

1) Run CintaNotes and activate "Help/Debug/Debug Logging"
2) Try to repeat the problem
3) This will produce the file named "log.N.txt" (either in CN folder,
   or in %APPDATA%\CintaNotes), where N is a number - please send the latest
   file (it will be the one with the max N) to support@cintanotes.com

Thanks!

Agreed this would be a necessary enhancement. Thanks

That's really weird. Any chance you could record this behavior in a debug log and send to me? Thanks in advance!

I wonder why it doesn't work for you.. Yes, Ctrl+BkSp is documented here: http://cintanotes.com/keyboard-mouse-shortcuts/

How many tags does the note have which is focused when you press Ctrl+BkSp?

Please also try making a new notebook with a couple of notes and 1-2 tags - does it work this way?
