Files Folders and Tabs

Files, Folders and Tabs

Opening and saving

Ctrl+N	New document, in a new tab
Ctrl+O	Open a file, in a new tab
Ctrl+S	Save (you are asked where the first time)
Ctrl+W	Close the current tab

The clock icon opens Open recent — the files you last opened or saved, newest first. The same list is on the editor's Windows taskbar jump list.

Opening a file that is already open activates its existing tab rather than opening it twice.

Tabs

One tab per open document. The tab shows the file's name; hover it to see the whole path (an unsaved document says it has no file yet).

A dot on a tab means unsaved changes. Closing a tab with unsaved changes always asks first — that applies to every way of closing, including the bulk ones below.

The tab right-click menu

Right-clicking a tab acts on that tab, not on whichever one is currently active:

Entry	What it does
Pin tab / Unpin tab	Moves the tab into or out of the pinned row
Close tab	Closes that one
Close all tabs	Closes everything, pinned included, leaving an empty workspace
Close all but pinned	Closes everything except the pinned row

On both bulk closes you are asked about each unsaved document in turn, and Cancel on any one of them stops there — keeping that document and everything not yet reached.

Pinned tabs

A pinned tab moves to a row of its own above the ordinary tabs. That is what pinning is for: a document that stays put through the comings and goings of the others, and that Close all but pinned spares.

Pinning is bookkeeping about the tab and nothing else — it never touches the document, never changes which tab is active, and never closes anything. Pins are remembered across restarts. Note that pinned is not "locked open": Close tab and Close all tabs still close a pinned tab.

Either row disappears entirely when it empties, except that the ordinary row stays visible while nothing at all is pinned, so you always have a tab strip.

The folder workspace

Open folder (the folder-with-arrow icon) points the editor at a directory and shows its Markdown files as a tree in the folder panel. It turns the editor into a lightweight knowledge base — a vault, a docs directory, a repository's docs/.

• Double-click a file (or select it and press Enter) to open it in a tab.
• Only Markdown files appear, and any folder with no Markdown beneath it is hidden — so a source repository shows you its documentation and nothing else.
• Within each folder, subfolders come first, then files, each sorted by name.
• The tree tracks the folder live: a file added, renamed or removed on disk shows up without you doing anything. The circular arrow beside the folder name rescans on demand.
• The open folder is remembered and reopened next time you launch.

Browsing the tree never changes any document, and the folder panel is not tied to the active tab — it keeps showing the folder even with no document open, so you can browse to one.

The folder panel and the outline share the left edge as two tabs of one dock, so neither costs you a whole column.
