Redo and Ctrl+c

[kruseio]

Would there be interest in adding redo and Ctrl+c?

• Ctrl+r: redo
• Ctrl+c: same as esc

[keys.normal]
...
C-r = "redo"
C-c = ["collapse_selection", "keep_primary_selection"]
...

[keys.insert]
...
C-c = ["collapse_selection", "keep_primary_selection"]
...

[keys.select]
...
C-c = ["collapse_selection", "keep_primary_selection"]
...
