Issue:
fish-like partial suggestion completion
Xonsh already supports the fish-like suggestion completion, which is great. I.e., on a greyed suggestion, typing the right arrow completes with the full suggestion.

One thing I miss though is the fish partial suggestion completion. In fish, if I am right, when a suggestion is provided, typing "alt + right_arrow" completes the suggestion only until the next separator. Great to use parts of a suggestion only.

Any way a partial suggestion completion with alt + right_arrow is either already available, or could be added? :) .

Discussion:
jnoortheen: Any reason using Ctrl+Right ? these issues mention Alt+Right
