Feature Proposal: Focus document body when opening a document via command line.

[kenaroik]

Is your feature request related to a problem? Please describe.
I call it a "feature", but you could consider it as a bug... When I open a document via command line (keyboad action) some other UI element than the document has the focus. I need to click into the document to be able to navigate via keyboard arrow keys.

Describe the solution you'd like
Focus the document on startup.

Describe alternatives you've considered
None.

Additional context
None.

Regards
kenaroik

Update: The same problem occures when switching documents using Ctrl+TAB ... the switch works, but some other UI element has the focus. Navigation using keyboard is not working.
