Feature idea: Keyboard shortcuts

[elimisteve]

• [x] ctrl-n to create new document/page
• [x] ctrls-s to save
• [ ] highlight + ctrl-k to turn highlighted text into a URL
• [ ] ctrl-k to bring up conveniently-autocompletable list of Backends just like Slack brings up list of channels
• [ ] ??? to bring up autocompleteable list of documents in current Backend
• [ ] alt-n to create a next bullet point at the same indentation level as the current one
• ??? to jump the cursor between

@jimmcgaw What would make this a productivity-lover's fantasy?
