Vim’s jump list tracks your movements through a file, allowing you to quickly return to previously visited locations. This is incredibly useful for navigating complex codebases or documents.

Think of the jump list as a breadcrumb trail of your editing journey. Every time you perform certain actions, Vim adds your current location to the list. These actions include:

• Using motions like G, n, N, /, ?, %, (, ), [[, ]], {, }.
• Deleting lines with dd.
• Changing lines with cc.
• Inserting text and exiting insert mode.

You navigate this history using two primary commands:

• Control-O: Takes you back in the jump list (older locations). Think “O” for older.
• Control-I: Takes you forward in the jump list (newer locations). Think “I” for inwards (returning). Mnemonic: Control-I is the opposite of Control-O.

Here’s an example:

Imagine your cursor is on line 1. You then jump to line 50 using 50G, then search for the word “function” using /function, and finally jump to the end of the file with G.

Now:

• Pressing Control-O once takes you back to the end of the file (where you were after G).
• Pressing Control-O again takes you back to the location of the word “function”.
• Pressing Control-O a third time takes you back to line 1.

If you then want to retrace your steps forward:

• Pressing Control-I would take you back to the location of the word “function”.
• Pressing Control-I again would take you to the end of the file.

You can repeatedly press Control-O or Control-I to navigate through your jump history. This allows for a very fluid workflow, enabling quick jumps between different parts of your file without having to manually re-navigate using line numbers or search patterns. It’s especially powerful when combined with other Vim features, like marks. You can set a mark with ma (where ‘a’ is the name of the mark) and then jump back to it with “a. Combine this with jumps and you can create complex but easily repeatable navigation patterns.

While simple to use, Vim’s jump list provides a powerful mechanism for navigating and revisiting locations in your code. Mastering its use will significantly enhance your editing efficiency.
