General Shortcuts

Line navigation
- Arrow keys
- Modifiers
  - ALT - move in ‘word’ increments
  - CMD - move in ‘line’ increments
  - SHIFT - selects items
- To enable these in ITerm
  - Settings -> Profiles -> Keys -> Key Mappings -> Presets -> Natural Text Editing
vim bindings
- I do not use these
- vim is considerably more effort to learn, but much more powerful
- If you’re interested in giving vim a go, have a look at the vim tutor, just type vimtutor into your terminal to access it
- vim bindings can be used in many places, other than just the vim editor
  - vscode
  - terminal
  - browser
    - vimium
      - more functionality than link hints, but more complicated
    - LinkHints
      - click links on the browser using just your keyboard

VSCode Commands

There are equivalents for these in XCode too (and probably the majority of editors)
CMD + P
- Fuzzy Find
  - allows you jump to files in the currently open workspace
- You can also use other vscode go-tos by typing the right symbol here
  - i.e. > for command palette commands, @ for go to symbol
- Open quickly seems to be the XCode equivalent
CMD + SHIFT + O / CMD + P - @
- Jump to symbols in the currently open file, i.e. functions/ interfaces/ classes
CMD + T / CMD + P - #
- Jump to symbols in the workspace, i.e. functions/ interfaces/ classes
- From what I can see, Open quickly in XCode seems to offer this functionality as well as being able to navigate files
CMD + SHIFT + P / CMD + P - >
- Able to do lots of things!
- If it’s an action you want to complete within vscode, there is probably a command for it in the command palete
- Keyboard shortcuts are also shown next to the command within the palette, giving you an easy way to learn the commands you use most
- VSCode extensions will often include their own command palette commands
- Examples
  - Controlling git
  - Running tests
  - Folding/ Unfolding code
  - Adding cursors to lines
    - The combination of additional cursors (whether created with the command palette, clicking, or with find/ replace) can be very useful in conjunction with command palette operations
  - Changing the case of text
  - Navigating vscode (i.e. switching to the source control tab)
- XCode seems to have Quick Actions which works in a similar way
- It seems like many applications are adopting this workflow more and more, it’s worth checking if any application you’re using has it, as it’s a quick way to speed things up

CMD + J
- Open/ close the bottom pane
CMD + B

- Focus breadcrumb
- The breadcrumb (at the top of the open file) shows you where the currently open file is located within the open workspace
- This can be navigated usually by clicking on e.g. the file name to navigate to another file in the same directory
- For example, if you are in a directory with forecast.go and forecast_test.go, and you want to navigate to the test file, this is a way of doing that
