+This & That
+===========
+
+Refer to 'that last thing', and 'the first thing':
+
+```bash
+fortune -l > file1
+cat !$  | tr -d u
+diff !^ !$
+```
+
+**NB:** this can go wrong:
+
+```bash
+ls -l file1 file2
+cat !^
+```
+
+Done
+----
+
+`<C-d>`
+
+- If you have a command, Control + d will execute the command.
+- If you have nothing, `exit`.
+
+Input Run-Commands (`~/.inputrc`)
+=================================
+
+Alias Expansion
+---------------
+
+```bash
+echo '"\C- ": shell-expand-line' >> ~/.inputrc
+exec bash
+```
+
+Now you can expand all aliases with 'Control + Space'.
+Try just `ls`, then 'Control + Space'.
+
+Glob Expansion (`*`)
+--------------------
+
+```bash
+echo '"\C-x": glob-expand-word' >> ~/.inputrc
+exec bash
+ls *<C-x>
+```
+
+- Are you sure you want to delete that?
+    * `rm -r *<C-x>`
+- Clean up the Downloads folder:
+    * `rm Downloads/*pdf<C-x>`
+
+Arbitrary Commands
+------------------
+
+Use `\n` as a 'newline' character to automatically press `<Return>`.
+
+```bash
+echo 'Control-y: "| lolcat\n"' >> ~/.inputrc
+exec bash
+ls<C-y>
+```
+
+```bash
+Control-l: "\C-u clear -x && ls\n"
+exec bash
+cd /etc/<C-l>
+```
+
+Readline as Vi
+--------------
+
+```bash
+echo 'set editing-mode vi' >> ~/.inputrc
+echo 'set keymap vi-insert' >> ~/.inputrc
+exec bash
+```
+
+The prompt now works according to `vi`-motions.
+This goes much further than the bash-option, `set -o vi` ('set option: `vi`').
+It changes the cursor in the terminal, not just bash.
+
+Try:
+
+- `ls <C-n>`
+- `ls <C-p>`
+- Type some words.
+- `<Esc>0dw$p`
+- <Esc> to normal-mode, and go back with 'b', and forward with 'e'.
+- `4b` to step back four times.
+- `cE`
+- `<Esc>kcw`
+- ls -a<Esc>xxxx
+
+Works with `python` too:
+
+```python
+im<C-n>os<Return>
+os.li<C-n><Return>
+<Esc>kfn
+<C-d>
+```
+
+Fix Globs!
+----------
+
+If you tried the previous commands then they will not work any more, because the `vi`-commands overwrite the other commands.
+Remove them.
+
+```bash
+sed '/ vi/d' ~/.inputrc
+sed -i '/ vi/d' ~/.inputrc
+
+sed '1 i set editing-mode vi' .inputrc 
+sed -i '1 i set editing-mode vi' ~/.inputrc 
+sed -i '2 i set keymap vi-insert' ~/.inputrc 
+```
+
+Vi-sibility
+-----------
+
+The `readline` prompt becomes confusing if you don't remember if you're in insert or normal mode.
+But you can show the  current mode in the prompt:
+
+```bash
+echo 'set show-mode-in-prompt on' >> ~/.inputrc
+exec bash
+```
+
+Set new symbols for normal and insert mode:
+
+```bash
+echo 'set vi-ins-mode-string "  "' >> ~/.inputrc
+echo 'set vi-cmd-mode-string " "' >> ~/.inputrc
+```
+
+Fuzzy Sort
+==========
+
+Check your repos for `sk-im`, and install.
+The program is called `sk`.
+
+```bash
+FUZZY=sk
+```
+
+If you don't have it, `fzy` or `fzf` should work the same way.
+
+```bash
+FUZZY=fzy
+```
+
+Find some 'read-config' files to check out:
+
+```bash
+find . -maxdepth 2 -name "*rc"
+find . -maxdepth 2 -name "*rc" | $FUZZY
+```
+
+And read some:
+
+```bash
+PAGER='less -R'
+$PAGER "$(find . -maxdepth 2 -name "*rc" | $FUZZY)"
+```
+
+Make the change long-term:
+
+```bash
+alias rrc='$PAGER "$(find . -maxdepth 2 -name "*rc" | sk)"'
+alias | grep rrc= >> ~/.bash_aliases
+```
