Code review comment for lp:~uriboni/webbrowser-app/keyboard-navigation

Thanks for working on this, now the desktop experience is definitely better!

I leave some impression, don't know if you want to fix in this branch or in a latter one

Some comments:
- I expect to navigate the history with arrows after I open it with CTRL+H
- If I navigate to a page I can scroll with arrows (good!), then I open history with CTRL+H, then I press ESC, arrows don't do anything anymore. I expect they still scroll the page

Some more keybinding I would like:
- CTRL+SHIFT+T to reopen the last closed tab
- ALT+F (as on Chromium) to open the menu and then arrows to navigate it
- F11 to go fullscreen (but this I think requires some other works)

I took a fast look to the code and, apart of a little typo I left a comment inline, looks good to me, except Python I didn't review due my lack of knowledge of Python.

Cool work!
