Keyboard shortcuts and navigation

[Cankyre]

Describe the feature

The keyboard navigation, especially when navigating PGN files, is a bit lacking. Here is a list of keyboard mappings that I'd like to see in En-croissant, including those from #11 . A lot of these can also be included in the menu bar.

• Save as (Ctrl+shift+s)

• Replace move (Shift+Move)
• Play best computer move (Space)

• Clear shapes (Ctrl+L)

View
