¶Editing

e provides the editing primitives you expect from a modern code editor.

¶Creating & saving files

• ⌘N creates a new, empty untitled buffer — start typing right away.
• ⌘S saves; for an untitled buffer it opens a Save As dialog, then reopens the file with the right language, LSP, and git support.
• ⌘⇧S is Save As… for any buffer.

¶Line operations

Line operations act on the line containing the caret, or on every line touched by the current selection.

¶Comments

Toggle line comments for the current line or selection with ⌘/. The comment token is chosen from the file's language (// for Rust/JS/TS/PHP/C/Go, # for Python/Shell/TOML, and so on). Toggling again removes them.

¶Multiple cursors

• ⌘⇧D adds a cursor at the next occurrence of the current word or selection. Repeat to keep adding cursors, then edit them all at once.

¶Auto-closing brackets & quotes

As you type (, [, {, ", ', or `, the matching closing character is inserted automatically and the caret is placed between them. In addition:

• Type-over: typing a closing character when it already follows the caret steps over it instead of inserting a duplicate.
• Wrap selection: with text selected, typing an opening bracket or quote wraps the selection.
• Smart backspace: deleting the opening half of an empty pair removes both characters.
• Apostrophes after a word (e.g. don't) are not auto-closed.

Disable this behaviour with "auto_close": false in your configuration.

¶Auto-indent

Pressing Enter keeps the indentation of the current line, so new lines line up with the code above.

¶Rename

Press F2 to rename every whole-word occurrence of the identifier under the caret within the current file. (Project-wide LSP rename depends on the language server.)

¶Saving

• ⌘S saves the active file.
• With format on save and trim on save enabled (the defaults), the file is formatted via the language server and trailing whitespace is trimmed before writing.
• Auto-save writes dirty buffers after a short idle period.

See Configuration to adjust these.

¶Emmet

In HTML, Blade, Vue, Svelte and PHP files, type an Emmet abbreviation and press Tab to expand it (or run Emmet: Expand Abbreviation from the palette):

Supported: tags, .class, #id, [attr=value], {text}, child >, sibling +, grouping (), multiplication *N and $ numbering. The caret lands at the first sensible insertion point.

¶Encoding & line endings

The status bar shows the file encoding and line-ending style. Click the LF / CRLF indicator to convert the buffer. Non-UTF-8 files are detected on open (BOM or Windows-1252) and saved back in their original encoding.

¶Unsaved changes & external edits

• Closing a tab with unsaved changes prompts you to Save, Don't Save, or Cancel.
• If a file changes on disk (e.g. after git checkout), clean buffers reload automatically. If you have unsaved edits, a bar offers to Reload (discard yours) or Keep yours.
