Productivity shortcuts & settings

Iterm2

Shortcuts

Command + tab: open new tab
Command + number or Command + ->/<-: move between tabs (who needs tmux!!)
Command + d: open split pane horizontal
Shift + Command + d: split pane vertical
ctrl + d: close this iterm pane
Shift + arrow key: move between panes (I customized this by going to Preferences/profiles/Keys and add shortcuts for Previous Pane and Next Pane)
Cmd + K: equivalent to $ clear in terminal

Hotkey Window

To configure ITerm 2 hot key window.

Open iTerm2
Go to preference > Keys > Hotkey
“Create a Dedicated HotKey Window”
On the Hotkey, choose the shortcut by holding Ctrl and h. Then click ok to create
Ctrl + h to open use hotkey window
Set background image randomly. Download file from https://github.com/jamsyoung/iterm2-random-background to ~/Downloads. Then go to iterm2 Preferences/profiles/general and add the execution code osascript ~/Downloads/iterm2-random-background.scpt (I think osa means os Apple?) in “Send text at start”.

Cool things to configure

Configure iterms to either be transparent or use background image. (Preferences>profile>(select the correct profile)>windows)
Use the ubuntu colors! (Preferences>profile>colors)
Use ZSH_THEME="powerlevel10k/powerlevel10k" in the .zshrc file. May have to install oh-my-zsh.

Remap keys

https://apple.stackexchange.com/questions/89981/remapping-keys-in-iterm2 In iterm2, go to Preferences/keys/keybindings then we can add custom key binding. For example, I want to remap cmd + / to gc. I’ll do cmd + / in the keyboard shortcut, and select send hex code. To find out the hex code for gc, I use the app Key Codes in Mac and type gc in the app. The code is the last part of unicode. For example, g is 0x67 and c is 0x63.

Some random cool terminal apps

neofetch, screenfetch. Installed by brew.
go-nyancat https://github.com/NARKOZ/go-nyancat. Then use alias in zhsrc to map nyancat to cd ~/Downloads/go-nyancat && ./go-nyancat.
alias weather=’curl http://wttr.in/’.
w3m google.com to surf google from the terminal.
cmatrix https://github.com/abishekvashok/cmatrix.
fish: a cool terminal with stuff like auto-suggestion, syntax highlighting, and completion. We can get the same thing in zsh by installing a bunch of zhs plugins (https://www.youtube.com/watch?v=SVh4osULjP4&ab_channel=DanielLaera).
Chrome

Shortcuts

Cmd + t: open new tab
Cmd + n: new window
Cmd + shift + n: new igconito window
Cmd + number: move between tabs
https://support.google.com/chrome/answer/157179?hl=en&co=GENIE.Platform%3DDesktop#zippy=%2Ctab-and-window-shortcuts
- ctr + tab: jump to right tab
- Ctrl + shift + tab: jump to left tab
cmd+y: history

Extensions

Use Ubuntu theme
Use https://chrome.google.com/webstore/detail/shortkeys-custom-keyboard/logpjaacgmcbpdkdchjiaagddngobkck?hl=en extension to build custom

shortcuts. - shift+left, shift+right to go back and go forward (in url) - command+left, command+right to move between tabs. - Note: there’re some issues with command on a new tab: https://github.com/mikecrittenden/shortkeys/issues/44. The solution is to use Chrome native shortcut UI via this extension. See bottom of this page https://github.com/mikecrittenden/shortkeys/wiki/How-To-Use-Shortkeys. Basically, need to go to chrome://extensions/shortcuts and configure the shortcut there instead. chrome://extensions/configureCommands

Mac

Shortcuts

Open spotlight search Cmd + Space
Open new iterms at this folder Shift + Cmd + Option + N
Undo Command + Z
Redo Command + Shift + Z
In finder, do Shift + Cmd + G: to be able to navigate to hidden folders
Cmd + Tab switch between apps.

Cool apps

Spectacle

Window manager. It shows all the shortcuts in the app. Move left/right, move top left/right, move bottom left/right, move center, move full-screen

Mac Spaces & Mission Control

Ctrl + Up: see the mission control to create new workspaces
Ctr + <-/->: Moving between spaces

List of cool apps: https://www.youtube.com/watch?v=RNqDkF17ogY&t=411s&ab_channel=devaslife

Alfred

Replacement for Spotlight search.

Raycast

Free alternative for Alfred

CursorEffect 2

Make the mouse look pretty

Keycastr

Capture the typed keys

Display stuff like weather, cpu, memory usages in the top bar.

InsomniaX

Disable lid sleep. Used to be good for stuff like training ML models over night on Jupyter notebook, and we want to disable Mac autosleep.

Aerial companion

Beautiful desktop and screensaver based on Apple 4K video TV.

Dozer

Arrange the menu bar/hide application. Free alternative to Bartender.

Slick app to display weather / current temperature on the menu bar.

VSCode

Shortcuts

To change keyboard shortcuts. Open command palette and search for keyboard shortcuts

Trick to find out what the command’s name for a key binding. E.g. I don’t know what the name of the command associated with Cmd + W. Go to keyboard shortcuts, search for tab and pick a random tab command that has no key binding. Then, try to add Cmd + W key binding to it. VSCode will warn that there are already existing commands and you can see what they are. Alternatively, put the command in bracket and search in keyboards i.e. search for "cmd + w"

Useful reference: https://zellwk.com/blog/useful-vscode-keyboard-shortcuts/

Open command Palette Cmd + Shift + P
Go to File (Search for files in this project) Cmd + p
Toggle the sidebar Cmd + b
Go to symbol in workplace (search for variables) Cmd + t
Search
- Cmd + f: within a file
- Cmd + Shift + F: within all files (in this project)
File: New Untitled File Cmd + n
Delete file “Cmd + Delete” when clicking on the file from the explorer (Cmd + b)
Move between panes Cmd + 1, Cmd + 2
- Custom shortcuts: Cmd + left, Cmd + right (arrow key) to move between windows (name of commands view:focus left/right editor group.
Close window (Delete Tab) Cmd + W
split editor Cmd + \
Open new external monitor Shift + Cmd + C
- Change the default terminal in vscode to iterm https://stackoverflow.com/questions/29957456/change-default-terminal-app-in-visual-studio-code-on-mac
Jump tabs Within a pane
- Shift + Cmd + [
- Shift + Cmd + ]
- Custom map now to shift+left, shift+right (name of commands view: open previous/next editor)
Resizing panes. I customized it to
- Shift = (i.e. + sign) to increase current view size (name of command).
- - (i.e. - sign) to decrease current view size.
Move lines Option + up or down
Select mutiple lines Shift + arrow keys
Move lines up down Option + up/down arrows
Move files from one split window to another (https://stackoverflow.com/questions/44018175/hotkey-to-move-a-tab-from-one-of-two-split-editors-to-another)
- workbench.action.moveEditorToNextGroup View: Move Editor into Next Group: remapped to -> + ->
- workbench.action.moveEditorToPreviousGroup View: Move Editor into Previous Group: remapped to <- + <-
highlight code and then do Cmd + / to comment or uncomment code (generally works for sublime and other editors than Vscode as well!)

Configure

Make vscode transparent by installing vibrancy. Can see through the background
Use bearded or spotify or github themes
Use the (anime) background extension
(Of course) use vim extension (with vimrc linked! Can config this in user settings)
Use github copilot (It’s insanely smart. Holy smoke!)
Use extensions for specific language (e.g. Python, Javascript suppport have separate extensions).

Vim

Shortcuts

Move to end of line $
Move to the end of line and enter insert Shift + a
Move to the beginning of line 0
Move to the beginning of line and enter insert Shift + i
New line below and insert o
New line above and insert Shift + o
All the yank and delete stuff
- y, d
- yy: yank line
- dd: delete line
  - Shift-D (preferred) or Shift-$: delete the rest of the line
- p: paste
- yw: yank word
- yiw: yank (inner) word.
- Similarly,
- dw, diw, vw, viw (visual select word).
  - NOTE: we can use cw, cc instead of dw, dd to delete AND jump into insert mode
The difference between yw and yiw is that for yw you need to be at the beginning of the word. For yiw, you can be in a character inside a word.
Some cool thing to do with v,i,d,c. Say, I want to delete the args x,y,z of def fun(x,y,z). I can go to somewhere within the bracket and do di( or di) to delete or ci( or ci) to delete and enter insert mode (so that I can type in other args e.g.).
Undo u
Redo Ctrl + r
Go to definition (e.g. of a function, variable…) gd
Go to the file under cursor: gf (useful to look up import statements). Can use ctrl+w gf to open the file in a new tab or ctrl+w f to open in new split
next tab: gt
prev tab: gT
Jump back to prev location (“old” for old) Ctrl + o
Jump forward to next location Ctrl + i
Jump back to the prev files: ctrl + ^. Useful for toggling between two files that you’re editting at once. (useful when first used with fzf to open the second file).
Code folding
- zc: close
- zo: open
- za: toggle the the fold
- zr: reduce fold level (open)
- zm: increase fold level (close)
- zR: open all folds
- zM: close all folds
Go to the top gg
Go to bottom Shift + g
Move to next/back brackets Shift + [, Shift + ]
Search the current word under cursor. (jump to the next occurence) *
Repeat last change in normal mode (work for stuff like dw) .
@: repeat last command entered with :something.
When searching
- n: to next
- shift + n : to go back
When doing auto-completion
- shift + n: go to the next suggestion
- shift + p: previous suggestion
Insertion
- i: insert before cursor
- a: insert after cursor
- s: delete word and enter insert mode
- x: delete word
- Shift + i: insert beginning of line
- Shift + a: insert end of line
- f + character: jump on that character within this line
- t + character: jump to before character within this line
  - as usual in vim, Shift + something is going backward so we can do stuff like shift + f, shift + t, shift + tab (in suggestion) and shift + s (in the sneak pluggin)
- Use ; to repeat the t and f jumps. , to go backward. https://stackoverflow.com/questions/10340562/vim-repeat-find-next-character-x
e: get to the end of a word
%: jump to matching brackets like (, ) or {, }
tip: deleting args of function?
- when already at the beginning of the bracket. Use d t then ) (or whatever bracket symbol you want).
- At the beginning of the line, hit “shift + %” to jump to the bracket. Then ca] to delete everything inside the bracket including the brackets themselves. Use ci] to delete only the things inside and keep the bracket. c is for delete and enters insert mode. Replace ] by whatever bracket type you have (e.g. ), })
Ctrl + a: increment a number under cursor
Ctrl + x: decrement a number under cursor
Shift + ~ : toggle capitalization of word
Capitalize the whole word:
- Shift + v: to visualize highlight the word
- Then, Shift + U: to capitalize the word
Marking
- use ma to mark the location of the current line to register a.
- Then later use 'a to go back to that location.
- Use capital letter (e.g. mA) to mark across files!

Commands

Panes

:sp or :split for horizontal pane split
:vs or :vsplit for vertical split
:q or Ctrl+w C to close the pane
Ctrl+w s: horizontal split
Ctrl+w v: vertical split
ctrl+o: close every panes except the current one
ctrl+w =: equal size panes
ctrl+w r: rotate panes (switch the positions of the panes)

Sourcing files

:so nameOfTheFile in vim to source a .vimrc or something.vim file or :so % to source the current file

Autocomplete

Ctrl+n (next) and ctrl+p (prev): to bring up vim built-in autocomplete
Highly recommend: install coc (https://www.youtube.com/watch?v=OXEVhnY621M&t=3s&ab_channel=ChrisAtMachine)

Macros

Macros: combinations of keys

Store macros to register

qa (store to register a)
then type some command
q finish recording macro
@a repeat last op from register

Terminal

https://www.youtube.com/watch?v=8m5t9VDAqDE&t=122s&ab_channel=ThePrimeagen Neovim (and vim) has terminal. Use ctrl+\ ctrl+n to leave the terminal (insert) mode. Do :terminal to open in new tab or :split | terminal or :vsplit | terminal to open in new split. Trick: (Primageon) when there’s an error message coming from file abc.xyz we can put the cursor under the file and hit ctrl+w f to go to that file

Packages

Use Vundle https://github.com/VundleVim/Vundle.vim to install packages. Usually, we put Plugin "something" in .vimrc within the Vundle bracket, then do :so % and :PluginInstall. Then the package is ready to use! We can even edit the package in ~/.vim/bundle/SpecificPackagename.

Use fzf for fuzzy finder. Good resource: https://www.youtube.com/watch?v=on1AzaZzQ7k&ab_channel=ChrisAtMachine

We can even use fzf in terminal. See .zshrc files for more. Basically download key-bindings.zsh and completion.zsh files from https://github.com/junegunn/fzf/blob/master/shell/ and source them in .zshrc as
https://github.com/marlonrichert/zsh-autocomplete, https://github.com/zsh-users/zsh-syntax-highlighting, zsh auto suggestion

To set custom key binding, go to each plugin folder (e.g. .zsh/zsh-autocomplete) and modify vi .zshrc.

# # for fzf fuzzy finder. Download from https://github.com/junegunn/fzf/blob/master/shell/
 source ~/Downloads/fzf_zsh/completion.zsh
 source ~/Downloads/fzf_zsh/key-bindings.zsh
# # ctrl+r : search through command history
# # ctrl+t : search through files (NOT folder)
# # normally, alt+c search through folders. But iterm2 and Mac
# # are usually weird with alt/option key. https://github.com/junegunn/fzf/issues/164
# # A solution is to do `bindkey "ç" fzf-cd-widget` where "ç" is
# # the character from hitting alt+c. 
# # Issues: Mac search folder can't access `Documents` folder. https://github.com/junegunn/fzf/issues/2073
bindkey "ç" fzf-cd-widget
#
# # https://mike.place/2017/fzf-fd/#:~:text=fzf%20is%20a%20command%20line,find%20files%20and%20change%20directories.
# # Use fd with fzf. And now, we have access to `Documents` folder!
# # --hiden to search hidden files
# Also, see https://github.com/sharkdp/fd#using-fd-with-fzf
export FZF_DEFAULT_COMMAND="fd --type file --hidden --follow --color=always --exclude .git"
export FZF_DEFAULT_OPTS="--ansi"
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
# https://github.com/sharkdp/fd. Use "-H" to search hidden 
# folders
export FZF_ALT_C_COMMAND="fd -H -t d"

Tcomment_vim: In visual mode, type gc to comment/uncomment code block. But most other editors use cmd + / to comment code so I map cmd + / to gc using the iterm2 trick. (see above in iterm2 remap trick). Note that Vim also doesn’t support the cmd key.
Vim_airline: for awesome status bar at the end.

Install color theme

Download a something.vim from github. Then put that into ~/.vim/colors. Then, we can use “:colorscheme something” to set the color.

Configure the file .vimrc in the root directory

Neovim

Neovim also supports github copilot! https://github.com/github/copilot.vim. It’s also easy to sync vim and neovim configs https://vi.stackexchange.com/questions/12794/how-to-share-config-between-vim-and-neovim. Only need to put the following

set runtimepath^=~/.vim runtimepath+=~/.vim/after
let &packpath=&runtimepath
source ~/.vimrc

in ~/.config/nvim/init.vim file.
