Learn These Keyboard Shortcuts To Become A VS Code Ninja

Recently, I wanted to limit mouse usage when programming in Visual Studio Code since I found interacting with the IDE through a cursor distracting and a major flow-breaker — so, I tried navigating VSC with keyboard alone.

Here, I would like to present some of the shortcuts that I have found to best increase productivity. Go ahead, open Visual Studio Code and let’s get started.

Splitting and focusing

Unless you are working on a very small screen, chances are you split your IDE into two or three views to switch more smoothly between files.

Splitting

To split the editor, you can use ctrl + \ (⌘ + \).

Splitting The VS Code Editor

There’s no limit to how many times you can split the editor, but I doubt you will ever want to have more than three views open; it is just not practical beyond that. You can switch between views using ctrl + 1 (⌘ + 1), ctrl + 2 (⌘ + 2), and so on. Alternatively, you can switch between tabs (and, by extension, between views) using ctrl + page up / page down (⌘ + page up / page down).

Focusing

Having split the editor, we ended up with the same file open in multiple views. Now we would like to focus the explorer panel. We would like to change this without touching the mouse. Also, it would be nice to focus different views without touching the mouse, too.

To focus the explorer panel we use ctrl + 0 (⌘ + 0). We navigate the panel using the up and down arrows. Using the enter key, we open a selected folder or file.

By default, there are two views: the explorer panel and the code view. The code view can be focused by using ctrl + 1 (⌘ + 1). If we create more views by splitting the editor, we use ctrl + 2 (⌘ + 2), ctrl + 3 (⌘ + 3), and so on for the respective views. We can also switch between consecutive tabs with ctrl + page up / page down (by default, this command isn’t defined on macOS).

Note that this will only work when VSC has access to the whole folder, and only when you are working with an open folder — not individual files.

Focus Explorer Panel

Alternative approach

There’s also a slightly different approach to selecting files that are farther in the list from the one currently open. We can use ctrl + p (⌘ + p), which opens up a search bar where we type in either a filename (http.service.ts) or a full path (src/services/http.service.ts).

Alternate Method To Select Files

Using the file history

We often don’t work with all the files in the project at once; we simultaneously work with two, maybe three at most. To shorten the time it takes to switch between them (if we don’t have enough screen space to split the editor), we can use the file history.

File history, as the name implies, saves the files we last used and provides a quick way to restore them. In VSC we use ctrl + tab to switch between the last opened files.

While this is indeed very efficient, there is yet another way which, one might argue, is even faster. By using alt + left / right arrows (ctrl + shift + - / ctrl + -) we can switch directly to the previous/next file in the file history.

Traversing the code

Now that we know how to navigate the files, let’s focus on the way we move around the code.

Making use of an outline

In the explorer panel, you can click the Outline section to have a code’s outline displayed. While the feature itself is amazing in that it lets us see a more general view of the code, we can also use it to quickly move around.

By using ctrl + shift + o (⌘ + shift + o), we can bring up the command palette, where we can choose the part of the outline we would like to jump to. After choosing the definition with an up/down arrow, the appropriate piece of code is highlighted for us, making it easier to get where we want to go.

Outline Section In The Explorer Panel

The same feature could also be used to search the whole project for a given piece of code. By using ctrl + t (⌘ + t), we again bring up the command palette, where we can now type the name of a variable/function/etc. to search for.

Searching For A Specific Function In The Outline Section

Straight to a given line

Imagine we want to jump straight to a specific line — for example, when there’s an error pointing to it. To jump to a line with a specified index, we can use ctrl + g.

Jumping Straight To A Specific Line

Jumping back

Often we want to fix something quickly in one place of the code and jump right back to where we were before. This we do using ctrl + u (⌘ + u), which takes the cursor back to where it was prior to the jump.

Beginning and end of a file

To jump to the beginning or the end of a file we can use ctrl + home (⌘ + up) and ctrl + end (⌘ + down) respectively.

Definitions and references

Have you ever searched for a definition by hand or by ctrl + shift + f (⌘ + shift + f)? If you have, then you know how annoying that can be. VSC has a great shortcut for that!

Jumping to the definition

We can jump to the definition of a function or a variable currently highlighted using F12.

Peeking at the implementation

Often we only want to have a quick peak at the implementation of, say, a function. Ideally, we don’t want to open another file just to check a few lines. By using alt + F12 (option + F12), we can peek at the implementation of a highlighted function right there next to the cursor. Once we’re done, we just press esc.

Peeking At Implementation

Peeking at references

There’s also a shortcut for peeking at references of a symbol in a similar manner — right next to the cursor. We do this with shift + F12 (⌘ + k and F12).

Peeking At References

In both cases, we can use the up and down arrows to choose the definition we would like to see or jump to.

Changing the name of a symbol

Changing the name of a given symbol (e.g., the name of a function) throughout the whole project can be tedious. It is usually done with ctrl + shift + f (⌘ + shift + f) — we manually replace each usage of the symbol.

This can be done faster with the F2 shortcut. It prompts a window where we type the new name of a currently highlighted symbol, and that’s it — every occurrence has now been replaced with the new name.

Changing The Name Of A Symbol

Taking a closer look at errors

When there’s something wrong with our code, VSC underlines it with a red line. Usually, we could just hover over the code with the mouse cursor and see what’s wrong. We can, however, do it much faster by using F8.

Examining Errors

We can leave the “error mode” by clicking the esc key.

Intellisense

Hover

As was the case with the errors, when we hover over a symbol, VSC shows us its simplified definition. To achieve the same result with the keyboard, we have to set up our own shortcut.

We can set our own shortcuts by using ctrl + k (⌘ + k) and then ctrl + s (⌘ + s), which will open the shortcuts settings view.

Setting The Show Hover Shortcut

Then search for the Show hover action:

Setting Custom Shortcut For Show Hover

And set it to your preferred shortcut. I have chosen alt + shift + s.

The shortcut in action:

Showing recommended actions

Sometimes VSC is able to fix our problems by, for example, importing the code we forgot to import ourselves or removing unused code. To see the available actions for the currently highlighted code, we can use ctrl + . (⌘ + .).

Showing Recommended Actions

Selecting code

Code is made of blocks, be it a body of a function or an if block. Sometimes we want to select the whole thing and, say, remove it without worrying about where the block begins and ends.

The alt + shift + left / right (⌘ + ctrl + shift + left / right) shortcut makes it a breeze to select pieces of code based on scope. Repeated use of this shortcut makes the selection appropriately bigger or smaller.

Selecting Code

Integrated terminal

With Visual Studio Code opened in the full-screen mode, it is often convenient to have a terminal right there with us. Switching between the terminal and code calls for a few shortcuts of its own.

Opening a terminal

To open a terminal, we use ctrl + `.

Opening A Terminal

To open more terminals, we use ctrl + shift + `.

Splitting it up

Terminal, just like the editor, can be split up into panels. For this we use ctrl + shift + 5.

Splitting The Terminal

Focusing

To focus on a terminal, while in the editor, we use ctrl + `. If we use ctrl + ` while the terminal is focused, we can toggle its state from shown to hidden.

Focusing split panels

Once we are focused on the terminal, we can use alt + left/right (⌘ + option + left / right) to switch focus between split panels.

Bonus

Here are some terminal shortcuts I found to be very helpful.

Killing a terminal

Killing a terminal can be achieved by clicking the trash icon in the top-right corner of the terminal, but in order for it to be a mouse-free experience, we have to set up a shortcut.

While in the shortcuts settings input, type in “workbench.action.terminal.kill” and then click on it to set up the shortcut. I have chosen to use ctrl + shift + x, but whatever works for you is fine.

Setting A Shortcut To Kill A Terminal

Maximizing a terminal

Sometimes, when there’s a lot of logs coming in, we would like to temporarily make the terminal larger. Same spiel as before, but in the settings, type workbench.action.toggleMaximizedPanel. Here, I have chosen to put it under ctrl + shift + q.

Everything else

In case you don’t know what the shortcut is for something, you can always open up the command palette with ctrl + shift + p (⌘ + shift + p) and type in what you want the shortcut to do, e.g., “open terminal.” Most of the time, it will show you the correct action with the shortcut next to the name.

Summary

The key to mastering these shortcuts is consistency. Try to implement them gradually, and before you know it, you’ll find yourself relying less and less on the mouse, which in turn will make your coding experience much smoother and more efficient.

Plug: , a DVR for web apps

LogRocket is a frontend logging tool that lets you replay problems as if they happened in your own browser. Instead of guessing why errors happen, or asking users for screenshots and log dumps, LogRocket lets you replay the session to quickly understand what went wrong. It works perfectly with any app, regardless of framework, and has plugins to log additional context from Redux, Vuex, and @ngrx/store.

In addition to logging Redux actions and state, LogRocket records console logs, JavaScript errors, stacktraces, network requests/responses with headers + bodies, browser metadata, and custom logs. It also instruments the DOM to record the HTML and CSS on the page, recreating pixel-perfect videos of even the most complex single-page apps.
