What it does |
| Default agent |
The agent listed first in the intercom, marked Last used. Follows whichever you started last, until you pick one. |
| Setting |
What it does |
| Warm start |
Keeps OpenMarkdown running in the menu bar (the system tray on Linux and Windows) after you close the window, so files reopen instantly. |
| Show in menu bar only |
No Dock icon once the window is closed. macOS only. |
| Command-line tool (openmd) |
Puts openmd on your PATH, for agents and scripts in your own terminal. macOS and Linux. |
| $VISUAL editor |
Adds export VISUAL="openmd --wait --source claude" to your shell's startup file, in a marked block it can remove again. New terminals then open OpenMarkdown when a tool asks for an editor (Claude Code's ⌃G, for one). It never overwrites a VISUAL you set yourself. See $EDITOR handoff. macOS and Linux. |
| Default app for .md |
Makes OpenMarkdown open .md files when you double-click them. Turning it off hands them back to the app before. macOS only. |
| Connect your agent |
The sentence and commands from Connect your agent, ready to copy. macOS and Linux. |
