The handy REPL command prompt ] understands environment variables (like `$PWD`). Refer to your shell's documentation (e.g. `BASH_ENV` for bash, `~/.zshenv` for zsh) to use aliases and functions. To fuzzy-select commands from your shell history at the command prompt and issue them after editing (like [fc](http://manpages.ubuntu.com/manpages/bionic/man1/fc.1posix.html)), copy the plugin `fzhist` (as `h` maybe?) in your `$PATH`.
+The native command prompt remembers only the last executed command in the current session. To access and use the shell's history add a shell function similar to:
+
+```
+h ()
+{
+ fzf <~/.zsh_history | tr -d '\n' | xsel -bi
+}
+```
+
+Then paste the selected command at the prompt using Ctrl-Sihft-V, optionally edit and run.
