Legacy Editor Shortcuts

This page lists the keyboard shortcuts and quick actions available in the legacy markdown editor.

It uses the same simple style direction as the vendor downloader page so it stays lightweight and consistent.

`Ctrl` on Windows and Linux maps to `Cmd` on macOS in the editor shortcut logic.
The top bar now contains most app-level actions like file, edit, view, and help commands.
The toolbar is mainly for markdown insertion and formatting helpers.

Keyboard Shortcuts

Shortcut	Action	Notes
`CtrlN`	New file	Clears the editor after confirmation if content would be lost.
`CtrlO`	Open file	Opens the browser file picker for markdown or text files.
`CtrlS`	Save file	Downloads the current document using the active filename when available.
`CtrlZ`	Undo	Moves backward through the local undo history.
`CtrlShiftZ`	Redo	Reapplies the most recently undone change.
`CtrlB`	Bold selection	Wraps the selected text in `**` markers.
`CtrlI`	Italic selection	Wraps the selected text in `*` markers.

Toolbar Actions

Control Group	Action	Best Use
Bold / Italic / Strike / Code	Inline formatting	Applies quick emphasis and inline code without typing markers manually.
H1 / H2 / H3	Heading insertion	Adds heading markers at the start of the current line.
List / Numbered List / Quote	Block structure helpers	Useful for drafting notes and outlines quickly.
Link / Image / Table	Template insertion	Creates markdown snippets for common content types.

Menu Guide

Menu	Contents	Use
File	New, Open, Save, Print, About	Document-level actions and version details.

Notes

The editor only implements the shortcuts listed above directly in JavaScript.
`Esc` closes an open top-bar dropdown menu.
Some features still use prompt dialogs because this is the legacy editor line.
