Ctrl+R History Search in PowerShell (PSReadLine)

PSReadLine can replicate bash's Ctrl+R, and its HistorySearch functions filter history as you type — most users never enable them.

Bind ReverseSearchHistory to Ctrl+r and HistorySearchBackward to UpArrow with Set-PSReadLineKeyHandler, then store it in $PROFILE.

01Command

Command
$ Set-PSReadLineKeyHandler -Key Ctrl+r -Function ReverseSearchHistory ; Set-PSReadLineKeyHandler -Key UpArrow -Function HistorySearchBackward

02What it does

PSReadLine stores an unlimited, persistent history file, but its best features are opt-in key handlers. ReverseSearchHistory gives incremental Ctrl+R matching, while HistorySearchBackward on the Up arrow is even better: typing a prefix like 'docker' then pressing Up cycles only through commands starting with it. Put the bindings in $PROFILE so they load in every session.
