Good catch.
A new release just went out that makes a few changes to this:
- Keyboard shortcuts are now automatically disabled when you're editing a document
- Enabling/disabling keyboard shortcuts (across all pages) is now a setting in your account settings page
- Side-note: keyboard shortcuts have been expanded for all premium page types also, not just free ones :)
That should help, so you shouldn't be accidentally whisked away to other pages while writing now. Do let me know if it's still happening to you anywhere though, there might be some browser-specific bugs to hammer out still.
The "Edit" button on Documents opens up in a new tab because the sidebar is hidden by default and originally some people complained that they were losing tabs but… I think the design's matured enough that I can revert that soon and keep all our tabs nice and clean. I'll straighten that out soon.
Thanks!
