Tabs

Every open document gets a tab above the editor. The active tab is marked with an accent bar and a bold name.

Unsaved changes

A dot on a tab marks unsaved changes, its name is shown in italics, and the tab's accessible name says "(unsaved)". The status bar and the window title show it too. If you close a tab or quit with unsaved changes, Markpion asks whether to Save, Don't Save or Cancel.

Switching and arranging

Action	Shortcut
Next tab	Ctrl+Tab
Previous tab	Ctrl+Shift+Tab
Close tab	Ctrl+W (Cmd+W on macOS)
Reopen closed tab	Ctrl+Shift+T (Cmd+Shift+T on macOS)

• Drag a tab left or right to reorder it.
• Long file names are shortened with "…"; hover a tab to see its full path.
• When two open files have the same name (say two README.md), each tab also shows, dimmed, the end of its folder path that tells them apart: docs and notes, or api/docs and web/docs.
• When more tabs are open than fit, scroll the tab strip with the mouse wheel. The active tab is always scrolled into view.
• When the tab list has focus, the arrow keys move between tabs.
• The + button after the last tab creates a new file.

Reopen closed tabs

File → Reopen Closed Tab reopens the most recently closed file; use it again for the one before, up to 20 files. Files that are already open again, or have been deleted, are skipped. Untitled documents that were never saved aren't kept.

Tab context menu

Right-click a tab for:

• Close, Close Others, Close to the Right, Close Saved and Close All (also File → Close All Tabs; each tab with unsaved changes asks first)
• Rename…: renames the file on disk, even when no folder is open (a document that was never saved offers Save As… instead). The new name stays in the same folder, an existing file is never replaced, and the Recent list follows the new name.
• Open Containing Folder… (for a file outside the open folder): opens the folder dialog in the file's folder, so you can open it in the Explorer
• Show in Explorer (for a file in the open folder; also Show Active File in Explorer in the command palette) expands the folders down to the file and selects it in the Explorer
• File History… (see Saving & recovery)
• Copy Path, Copy Relative Path (for a file in the open folder) and Reveal in File Explorer (Reveal in Finder on macOS)

Undo history

Each tab keeps its own undo history and cursor position while it's open, so switching tabs doesn't lose them.
