# Fish-like autosuggestions for zsh. This is implemented on top of zsh's
# builtin prediction feature by considering whatever is after the cursor
# to be 'unmaterialized'. The unmaterialized part is highlighted and ignored
# builtin prediction feature by treating whatever is after the cursor
# as 'unmaterialized'. The unmaterialized part is highlighted and ignored
# when the user accepts the line. To materialize autosuggestions 'TAB' must
# be pressed.

# Since predict-on doesn't work well on the middle of the line, many actions
# that move the cursor to the left will disable autosuggestions, so it should
# be less obtrusive than using predict-on directly
# that move the cursor to the left will pause autosuggestions, so it should
