The VS Code shortcuts worth learning first

Command Palette first, then work outward. Read the docs if one of these doesn't fire for you, keybindings drift by OS and by extension.

01
Cmd+Shift+P - Command Palette
every action in the editor lives behind this, learn it before anything else
02
Cmd+P - Go to File
03
Cmd+Shift+O - Go to Symbol
jumps inside the current file, use it on long files instead of scrolling
04
Cmd+K Cmd+S - Open Keyboard Shortcuts
05
Cmd+/ - Toggle Line Comment
06
Cmd+D - Add Selection to Next Match
multi cursor without the multi cursor menu. you will look this up again until it sticks
07
F2 - Rename Symbol
renames everywhere the symbol is used, not just the current line
08
F12 - Go to Definition
09
Cmd+. - Quick Fix
the lightbulb. most of the fixes it suggests are right, not all
10
Ctrl+` - Toggle Terminal
11
Cmd+\ - Split Editor
12
Shift+Alt+F - Format Document
only works if a formatter is installed for the language, silent otherwise
13
Alt+Left / Alt+Right - navigate back and forward
like browser back. works across files
14
Cmd+K Z - Zen Mode
15
Cmd+Shift+K - Delete Line
no need to select the line first
