The problem was in my system, keyboard shortcuts not working, sorry!

Couldn't delete the original post, else I would,

Thanks for your answer and for the amazing extension!

Ceasing the chance to ask you a question (if allowed):

I was reading here that you advice to make frequent backups of the TO folder,

I'm concern about data loss (as you can see by my first question :)

but, couldn't we re-import the data from this HTML file generated by the "Save as"?

Probably a dumb question, but, hey.. :)

Hi!

I just started trying Tabs Outliner and so far it looks great,

but before I feel safe enough to close my open tabs, I'd really like to make a backup, so,

I've been trying CTRL-S like crazy but without any results (nothing happens).

Any clues?

Thanks!
