VS Code tips & tricks

VSCodeShortcuts.md

• Code completion: just start typing and you will be offered anything that matches the syntax of the file’s language. (If not, press Ctrl + Space)
• Go to definition: quickly find any definition with “F12″ (depending on language). If you press Ctrl and hover over a an object, you can get a preview of its declaration so that you will not need to jump anywhere.
• Multiple selection and cursors: select all occurrences of any word with “Alt + Left Click.” You can add a cursor at the end of each line with “Ctrl + Shift + L,” allowing you to edit all occurrences of an object or symbol at once.
• Peek editor: you must not switch context; you can have a “sneak-peek” with “Ctrl + Shift + f10.”
• Format code: format your document with Shift+Alt+F
• Command file args: open file code mynewfile.js, open folders code c:\myfolder1 c:\myfolder2 c:\myapp\program.cs, start new editor session code -n (--new-window)
• Shift+Alt+Left Shift+Alt+Right shrink/expand selection

######Multi-cursor

• Ctrl+D selects the word at the cursor, or the next occurrence of the current selection.
• Ctrl+K Ctrl+D moves the last added cursor to next occurrence of the current selection. The two actions pick up the matchCase and matchWholeWord settings of the find widget.
• Ctrl+U undoes the last cursor action, so if you added one cursor too many or made a mistake, press Ctrl+U to return to the previous cursor state.
• Insert cursor above Ctrl+Alt+Up and insert cursor below Ctrl+Alt+Down now reveals the last added cursor, making it easier to work with multi-cursors spanning more than one screen height (i.e., working with 300 lines while only 80 fit in the screen).

######Comments actions

• Ctrl+K Ctrl+C now forces adding line comments.
• Ctrl+K Ctrl+U now forces uncommenting lines. (If multiple lines are selected, and not all of them have a line comment, the line comments will still be removed).
• Ctrl+/ toggles line comment as before, but now inserts the line comment tokens aligned with the indentation of the selected code. It also will leave empty or whitespace-only lines untouched. Ctrl+/ is also more forgiving with regards to selection state when toggling comments in languages which only support block comments, such as CSS or HTML. Toggle block comment Shift+Alt+A is also more forgiving related to selection state when toggling block comments.
