+# Vi-Commands
+
+Copy, move, and delete with vi-keys.
+
+```sh
+echo 'set editing-mode vi' >> ~/.inputrc
+echo 'set keymap vi-insert' >> ~/.inputrc
+exec bash
+```
+
+Try `ls <C-n>` and `ls <C-p>`
+
+Use python in vi-mode
+
+```sh
+echo 'export PYTHON_BASIC_REPL=true' >> ~/.bashrc
+exec bash
+```
+
+# Alias Expansion
+
+```sh
+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 (`*`)
+
+```sh
+echo '"\C-x": glob-expand-word' >> ~/.inputrc
+exec bash
+ls *<C-x>
+```
+
+Are you sure you want to delete that?
+
+```sh
+rm -r *<C-x>`
+```
+
+Clean up the Downloads folder:
+
+```sh
+rm Downloads/*pdf<C-x>`
+```
+
+# Arbitrary Commands
+
+Make a keyboard shortcut to type anything.
+Use `\n` as a 'newline' character to automatically press `<Return>`.
+
+```sh
+echo 'Control-y: "| lolcat\n"' >> ~/.inputrc
+exec bash
+ls<C-y>
+```
+
+Clear the screen and have a fresh look with `C-l`.
+
+```sh
+Control-l: "\C-u clear -x && ls\n"
+exec bash
+cd /etc/<C-l>
+```
+
+# Fix Globs!
+
+If you put the vi-commands in the wrong place in `.inputrc`, they stop working.
+Put them at the start:
+
+```sh
+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:
+
+```sh
+echo 'set show-mode-in-prompt on' >> ~/.inputrc
+exec bash
+```
+
+Set new symbols for normal and insert mode:
+
+```sh
+echo 'set vi-ins-mode-string "  "' >> ~/.inputrc
+echo 'set vi-cmd-mode-string " "' >> ~/.inputrc
+```
