Avid fish user since last 3 years. On feature I miss from bash is the `sudo !` to re-run previous command as sudo. Last time I checked fish didn't offer an equivalent. Either that or something similar will be useful
In fish Alt+Up does something similar, but repeated presses iterates over all words of all commands rather than last words of bash commands. A big improvement is you can type some chars first and then Alt+Up only gets words matching this substring — like Up but word granularity! (Closest bash key is Ctrl+Alt+I)
If you don't mind the differences, and want Alt+. muscle memory to work in fish too, do:
bind \e. history-token-search-backward
(plus Alt+Up doesn't work for me in linux console, Alt+. does)
Unlike bash, fish even expands it in place, allowing you to make changes.
