The only user-visible effect of this should be that "G" now works in show mode (previously it was unbound for no apparent reason). This shared keymap gives us one place to put global commands, which both forces us to think about what commands should be global, and ensures their bindings can't diverge (like the missing "G" in show).

This variable has three potential sets of values:

column.
