VS Code streamlines editing with 10 core shortcuts

VS Code's 10 core shortcuts streamline editing on macOS and Windows/Linux, according to a July 21 Dev.to guide [Dev.to]. The shortcuts include:

• Move line up or down: Mac Option + ↑/↓, Windows/Linux Alt + ↑/↓, which moves the current line or selected block without cut-paste cycles [Dev.to].
• Duplicate line: Mac Shift + Option + ↑/↓, Windows/Linux Shift + Alt + ↑/↓, copying the line above or below for repetitive code patterns [Dev.to].
• Select next occurrence: Mac Cmd + D, Windows/Linux Ctrl + D, expanding the selection to every matching token for instant rename [Dev.to].
• Select all occurrences: Mac Cmd + Shift + L, Windows/Linux Ctrl + Shift + L, grabbing every instance in the file after highlighting a word [Dev.to].
• Add cursor vertically: Mac Cmd + Option + ↑/↓, Windows/Linux Ctrl + Alt + ↑/↓, creating a new cursor for column-aligned edits [Dev.to].
• Multi-click cursor: Mac Option + Click, Windows/Linux Alt + Click, dropping independent cursors for simultaneous typing [Dev.to].
• Toggle line comment: Mac Cmd + /, Windows/Linux Ctrl + /, inserting or removing comment syntax appropriate to the file type [Dev.to].
• Find in file: Mac Cmd + F, Windows/Linux Ctrl + F, opening the search bar which can be expanded to replace mode [Dev.to].
• Quick open file: Mac Cmd + P, Windows/Linux Ctrl + P, starting fuzzy matching of any filename in the workspace [Dev.to].
• Split editor: Mac Cmd + , Windows/Linux Ctrl + , opening a side-by-side view for parallel editing [Dev.to].

These shortcuts reduce keystrokes per edit, speed up file navigation, and increase multi-cursor efficiency, as demonstrated in the guide [Dev.to]. For example, the line-move shortcut cuts the average edit sequence from eight keystrokes to two, and the quick-open command reduces the time to locate a module from roughly 5 seconds to under 1 second [Dev.to].
