+# Shortcuts
+
+*For Ubuntu's default keybinding settings (i.e Emacs keybindings)*
+
+## Insert previous arguments
+  - <kbd>Alt</kbd>+<kbd>.</kbd>: insert last argument from last command.
+  - <kbd>Alt</kbd>+<kbd>number</kbd>+<kbd>.</kbd>: insert #nth last argument from last command.
+  - <kbd>Alt</kbd>+<kbd>-</kbd> , <kbd>number</kbd> , <kbd>Alt</kbd>+<kbd>.</kbd>, **zsh:** <kbd>Alt</kbd>+<kbd>-</kbd>+<kbd>number</kbd>+<kbd>.</kbd>: insert #nth first argument from last command.
+
+*In Linux you can repeat commands to go back in history*
+
+### Example:
+
+Last command is:
+
+    mv foo bar
+
+  - <kbd>Alt</kbd>+<kbd>0</kbd>+<kbd>.</kbd>: insert first argument of last command = `mv`
+  - <kbd>Alt</kbd>+<kbd>2</kbd>+<kbd>.</kbd>: insert last 2nd argument of last command = `foo`
+  - <kbd>up</kbd> , <kbd>Ctrl</kbd>+<kbd>w</kbd>: last command without the last word = `mv foo`
+
+
+## Cut/Paste commands
+*(relative to cursor's position)*
+  - <kbd>Ctrl</kbd>+<kbd>w</kbd>: cuts last word
+  - <kbd>Alt</kbd>+<kbd>d</kbd>: cuts next word
+  - <kbd>Ctrl</kbd>+<kbd>k</kbd>: cuts everything after
+  - <kbd>Ctrl</kbd>+<kbd>u</kbd>, **zsh:** <kbd>Alt</kbd>+<kbd>w</kbd>: cuts everything before
+  - **zsh:** <kbd>Ctrl</kbd>+<kbd>u</kbd>: cuts the entire command *(In bash you can combine <kbd>Ctrl</kbd>+<kbd>u</kbd> , <kbd>Ctrl</kbd>+<kbd>k</kbd>)*
+  - <kbd>Ctrl</kbd>+<kbd>y</kbd>: paste characters previously cut with any **Cut command**. *In bash you can chain **cut commands**, and <kbd>Ctrl</kbd>+<kbd>y</kbd> will paste them all.*
+
+
+## Move cursor
+  - <kbd>Ctrl</kbd>+<kbd>left</kbd>: move to last word
+  - <kbd>Ctrl</kbd>+<kbd>right</kbd>: move to next word
+  - <kbd>home</kbd> or <kbd>Ctrl</kbd>+<kbd>a</kbd>: move to start of command
+  - <kbd>end</kbd> or <kbd>Ctrl</kbd>+<kbd>e</kbd>: move to end of command
+
+
+## Other
+  - <kbd>Ctrl</kbd>+<kbd>_</kbd>: undo last edit *(very useful when exceeding <kbd>Ctrl</kbd>+<kbd>w</kbd>)*
+
+## To see all shortcuts available
+  - **bash:** `bind -lp`
+  - **zsh:** `bindkey -L`
+
+# Custom shortcuts
+## Iterate through arguments
+*only works in zsh, and probably only Linux*
+
+### Description
+Insert any argument of a previous command by iterating one by one until selection
+
+### Setup Instructions
+run this:
+
+    autoload -Uz copy-earlier-word
+    zle -N copy-earlier-word
+    bindkey "^[:" copy-earlier-word
+
+*(to make this permanent, add it to your `~/.zshrc` and restart shell)*
+
+Now use <kbd>Alt</kbd>+<kbd>.</kbd> to go as back as you want, then use <kbd>Alt</kbd>+<kbd>:</kbd> to iterate through the arguments
+
+### Example:
+Last command is
+
+    echo 1 2 3 4 5
+
+- <kbd>Alt</kbd>+<kbd>.</kbd>: `5`
+- <kbd>Alt</kbd>+<kbd>.</kbd>+<kbd>:</kbd>: `4`
+- <kbd>Alt</kbd>+<kbd>.</kbd>+<kbd>:</kbd>+<kbd>:</kbd>: `3`
+- <kbd>Alt</kbd>+<kbd>.</kbd>+<kbd>:</kbd>+<kbd>:</kbd>+<kbd>:</kbd>: `2`
+- <kbd>Alt</kbd>+<kbd>.</kbd>+<kbd>:</kbd>+<kbd>:</kbd>+<kbd>:</kbd>+<kbd>:</kbd>: `1`
+- <kbd>Alt</kbd>+<kbd>.</kbd>+<kbd>:</kbd>+<kbd>:</kbd>+<kbd>:</kbd>+<kbd>:</kbd>+<kbd>:</kbd>: `echo`

+# Other examples
+
+## Common usecases
+Let's consider the last command to be:
+
+    mv foo bar
+
+<kbd>up</kbd> , <kbd>Ctrl</kbd>+<kbd>w</kbd>: last command without the last word = `mv foo`
+
+<kbd>Alt</kbd>+<kbd>0</kbd>+<kbd>.</kbd>: first argument of last command = `mv`
+
+# Limitations
+ "words" only includes `a-zA-Z` characters, so any symbol character will stop word-shortcuts.
+
+So if last argument was a url and you want to erase it with <kbd>Ctrl</kbd>+<kbd>w</kbd> it will be a pain.
+
+E.g: `curl -I --header "Connection: Keep-Alive" https://stackoverflow.com/questions/38176514/re-run-previous-command-with-different-arguments`
+
+To erase that **url** using <kbd>Ctrl</kbd>+<kbd>w</kbd>, you'd have to repeat it 12 times.
+
+
+---
+
+
+It would be great to have similar shortcuts that only stops at the **space character**
