    Tabs and Windows

Function
Shortcut
Use


Delete to start of line (favorite)
Ctrl + U
Use this to start over typing without hitting Ctrl-C


Delete to end of line (favorite)
Ctrl + K
Use this with command history to repeat commands and changing one thing at the end!


Repeat last command
Up Arrow
Cycle and browse your history with up and down.  Ctrl-R is faster if you know the string you are looking for.


Move back and forth on a line
Arrow Keys
This takes you off the home row but it's easy to remember


Move back and forth on a line by words
⌥ + Arrow Keys
Fast way to jump to a word to correct a typo or "run again" with minor changes


Delete previous word (in shell)
Ctrl + W
It's faster to delete by words.  Especially when your last command was wrong by a single typo or something.


Clear screen
Ctrl + L
This is telling the shell to do it.  When this doesn't work ⌘ + K will tell iTerm to do it which works when you aren't in a shell.  Use this instead of typing clear over and over.


Moving Faster

A lot of shell shortcuts work in iterm and it's good to learn these because arrow keys, home/end
keys and Mac equivalents don't always work.  For example ⌘ + Left Arrow is usually the same as Home
(go to beginning of current line) but that doesn't work in the shell.  Home works in many apps but it
takes you away from the home row.


Function
Shortcut


Move to the start of line
Ctrl + A or Home


Move to the end of line
Ctrl + E or End


Move forward a word
Option + F


Move backward a word
Option + B


Set Mark
⌘ + M


Jump to Mark
⌘ + J


Moving by word on a line (this is a shell thing but passes through fine)
Ctrl + Left/Right Arrow


Cursor Jump with Mouse (shell and vim - might depend on config)
Option + Left Click


Copy and Paste with iTerm without using the mouse


Function
Shortcut


Enter Copy Mode
Shift + ⌘ + C


Enter Character Selection Mode in Copy Mode
Ctrl + V


Move cursor in Copy Mode
HJKL vim motions or arrow keys

Copy actions goes into the normal system clipboard which you can paste like normal.
Search the Command History


Function
Shortcut


Search as you type
Ctrl + R and type the search term; Repeat Ctrl + R to loop through result


Search the last remembered search term
Ctrl + R twice


End the search at current history entry
Ctrl + Y


Cancel the search and restore original line
Ctrl + G


Misc


Function
Shortcut


Clear the screen/pane (when Ctrl + L won't work)

Broadcast command to all panes in window (nice when needed!)
⌘ + Alt +  I (again to toggle)
