Vim Diff

You can run vim in diff mode (like a git diff) using:

vim -d {file1} {file2}

Marks

Marks allow to jump directly to a specific line and column within the same document

• m[a-z] or m[A-Z]: set a mark at the current cursor position
• '{x}: jump to the beginning of the line {x} marked previously
• `{x}: jump to the exact position (line & column) {x} marked previously
• [': jump to the previous mark beginning of the line
• [': jump to the previous mark exact position (line & column)
• ]': jump to the next mark beginning of the line
• ]': jump to the next mark exact position (line & column)
• :marks: list all the current marks in the document
• dm{x}: delete the mark {x}
• `.: jump to where the last edit occured

Folding

• zo: open folding
• zc: close folding
• za: toggle open/close (ideal to replace both zo and zc)
• zM: collapse (minimize) all folding levels
• zR: expand (reveal) all folding levels
• zd: delete an existing fold (put your cursor in this fold first)
• zD: recursively delete an existing fold, that is, the current fold and all nested folds below

Manual folding

let you select manually your folding. E.g. zf, then you select 4 lines. Those 4 lines will become foldable. Likewise, zf5j will make the 5 rows below foldable together

Marker folding

Uses predefined markers that you set everywhere. By default, it's {{{ and }}} ("set foldmarker" to see it yourself). If you want to change it, "set foldmarker={opening_pattern}, {closing_pattern}, although not recommended. The idea behind the marker folding is to have a shortcut to add those markers where you want them, but it's very "vim" oriented and may bother other developers working on your project.

Indent folding

Groups lines with the same indent

Syntax folding

Close to indent, but will follow language logics, e.g. folding if blocks regardless of the indent below

Diff folding

Used when opening vim in diff mode, collapse everything similar between fileA and fileB
